1. Gemini 3.1 Pro

   Failed: Graded 3.3 of 5 on average (lowest 3).

   1. Should large cities ban all private cars from their downtown commercial districts during business hours? Supporters argue this will drastically reduce toxic air pollution and pedestrian fatalities, while opponents claim it will devastate local retail businesses and alienate commuters who lack reliable public transit.
   
   2. Is implementing a hefty daily congestion charge for driving into the city centre a fair way to manage traffic? Proponents state that financial penalties are the only effective method to force a shift to mass transit, whereas critics argue this creates an elitist system where only the wealthy can afford the convenience of driving.
   
   3. Should exceptions to car-free city centre zones be strictly limited to emergency vehicles, fully excluding private disability parking and commercial delivery trucks? One side insists that a zero-tolerance policy is necessary to realize true pedestrian safety and climate goals, while the other contends that this discriminates against mobility-impaired citizens and cripples urban supply chains.
   
   4. Should city centres eventually replace human-driven car access entirely with a mandatory, state-funded fleet of low-speed autonomous electric pods? Advocates argue this eliminates human driving errors and parking woes while maintaining point-to-point mobility, but detractors warn of massive technological infrastructure costs and the loss of personal freedom.
   
   5. Should municipal governments permanently close and repurpose all underground parking garages in the city centre to build subterranean public spaces and emergency shelters? Supporters believe we must aggressively force the end of car culture by physically removing its infrastructure, while opponents argue that destroying functional parking is economically reckless and ignores the reality of out-of-town commuters.

2. GPT-6 Luna

   Passed: Graded 4.7 of 5 on average (lowest 4).

   1. Should private cars be banned from city centres? Supporters argue that bans reduce pollution, noise, and traffic injuries; opponents argue they restrict access for people who cannot easily use public transport.
   
   2. Should city-centre drivers pay a congestion fee? Supporters say the fee discourages unnecessary trips and funds better transit; opponents say it unfairly burdens workers and small businesses.
   
   3. Should cities remove parking spaces in their centres to make room for bike lanes and wider pavements? Supporters argue the change makes streets safer and more welcoming; opponents argue it drives customers away and makes deliveries harder.
   
   4. Should residents of city centres be allowed to keep driving their cars into restricted zones? Supporters say residents need practical access to their homes; opponents argue that exemptions weaken the rules and preserve traffic problems.
   
   5. Should city centres prioritize car access during bad weather or public-transit disruptions? Supporters argue people need reliable alternatives when buses and trains fail; opponents say opening streets to cars can create gridlock precisely when conditions are most difficult.

3. GLM 5.3 Flash

   Passed: Graded 4.3 of 5 on average (lowest 4).

   1. Should private cars be banned from city centres entirely? Banning advocates point to cleaner air, safer streets, and faster public transport, while opponents argue that disabled residents, tradespeople, and shift workers would lose essential access.
   
   2. Should cities charge drivers a daily fee to enter the centre, like London's congestion charge? Supporters say pricing is the fairest way to cut traffic while funding buses and bikes, but critics counter that it becomes a tax on the poor while the wealthy drive as they please.
   
   3. Is converting city-centre car parks into housing and green space a sign of progress or short-sightedness? Reformers see obsolete asphalt as valuable land for homes and parks; others warn that removing parking will strangle local shops that depend on customers who drive in.
   
   4. Should city centres set a 20 km/h speed limit for all vehicles, with no exceptions? Safety campaigners argue that slower speeds save lives and make streets pleasant for walking, while opponents claim it grinds deliveries and emergency response to a crawl without meaningfully reducing accidents.
   
   5. Should cities invest primarily in car infrastructure or public transport for the next thirty years? Transit advocates say a bus or train moves far more people per metre of road and future-proofs the city, whereas road supporters argue that cars offer freedom and flexibility that transit can never match, especially outside rush hours.

4. Claude Haiku 5.5

   Passed: Graded 4.7 of 5 on average (lowest 4).

   1. Should cities ban private cars from their town centres entirely? Argue for the side of a shopkeeper on a high street whose trade depends on drivers stopping by, against a resident who has spent years breathing exhaust outside her window. Side A might argue that car-free zones revive local business by making streets safer and more pleasant to walk; Side B might argue that drivers, disabled residents and delivery firms lose access and that shops depend on parking.
   
   2. Is it fair to charge drivers a daily fee to enter the city centre? Argue for a transport planner who sees congestion charges as the only lever that works, against a delivery driver who says the charge punishes people with no other way to earn a living. Side A might argue that pricing reduces traffic and funds buses that serve everyone; Side B might argue that the fee falls hardest on low-income workers and small firms with no alternative.
   
   3. Should a city replace its central car parks with public green space? Argue for a retired gardener who wants trees and benches where the concrete sits now, against a councillor who argues that the parking income keeps the library and the swimming pool open. Side A might argue that green space improves health, cools the streets in summer and draws people into the centre; Side B might argue that without parking revenue, essential services will be cut and the public will lose more than it gains.
   
   4. Do electric cars solve the problem of cars in city centres? Argue for an engineer who believes battery vehicles will clean the air without taking space away from people, against a cyclist who says electric cars still clog the roads and kill pedestrians at the same rate. Side A might argue that zero-emission vehicles remove the worst pollution while keeping the freedom of driving; Side B might argue that electric cars keep the space, weight and danger problems of petrol cars, so the city still needs fewer cars, not just cleaner ones.
   
   5. Should cities let residents keep a car in the centre if they have no garage? Argue for a young family in a flat above a bakery, who needs a car for a child with a medical condition, against a neighbour who wants residential streets cleared for children to play. Side A might argue that people in old buildings without off-street parking should not be shut out of their own homes; Side B might argue that a few cars on every street keep the rest of the neighbourhood from ever becoming safe or quiet.

5. Gemini 3.8 Flash

   Passed: Graded 4.7 of 5 on average (lowest 4).

   1. Should municipal governments completely ban private combustion and electric vehicles from downtown commercial districts? Supporters argue this eliminates urban smog, slashes traffic deaths, and creates vibrant walkable spaces, while opponents contend it cripples local retail businesses and severely restricts access for elderly or disabled residents.
   
   2. Is the implementation of a high-rate congestion pricing toll the fairest way to reduce downtown traffic gridlock? Proponents assert that charging drivers directly funds public transit expansions and discourages non-essential trips, whereas critics argue it acts as a regressive tax that penalizes low-income suburban workers who have no reliable transit alternatives.
   
   3. Should heritage city centers replace roadway lanes and street parking with dedicated networks for bicycles, light rail, and pedestrians? Advocates believe this modernization reclaims historical streets for human-scale community living and tourism, but detractors maintain it paralyzes delivery logistics, harms emergency service response times, and disrupts the local economy.
   
   4. Should cities grant autonomous rideshare fleets unrestricted access to urban cores while banning all privately owned cars? Those in favor claim a coordinated, self-driving fleet optimizes traffic flow and eliminates the need for massive parking lots, while skeptics warn that an influx of cheap robotaxis will induce higher traffic volumes and kill off municipal subway and bus systems.
   
   5. In urban centers with high air pollution, is it justified to immediately outlaw all delivery vans and freight trucks during daytime business hours? Supporters hold that moving commercial freight to late-night hours safeguards public health and frees daytime streets for citizens, but opponents argue this drastically raises operating costs for small shops and forces unbearable late-night noise onto downtown residents.

   Passed: Graded 4.7 of 5 on average (lowest 4).

   1. Should Birmingham ban all private cars from its city centre by 2030? Backers would point to cleaner air and safer streets, while critics would argue that carers, disabled drivers and night-shift workers have no realistic alternative.
   
   2. Is a £15 daily congestion charge in Leeds fair if every penny goes to bus services? Supporters call it the only way to fund reliable public transport, opponents call it a tax on people who cannot afford to live near the centre.
   
   3. Should delivery vans and taxis be exempt from a car-free zone, as Marta argues for her corner shop on a pedestrianised street? She says her business dies without them, while residents say exemptions are the loophole that turns car-free into car-light.
   
   4. Should the bollards and planters of the low-traffic neighbourhood in Bristol's east side stay, even after residents on the boundary road signed a petition against them? One side sees quieter streets and children cycling to school; the other sees diverted traffic, longer ambulance routes and a decision made without them.
   
   5. Should a city centre's last multi-storey car park be demolished for housing, or kept for the shoppers and workers who still drive in? Developers argue the land is worth more as homes, while traders warn that removing the parking removes their customers.

7. GLM 5.3

   Passed: Graded 4.0 of 5 on average (lowest 3).

   1. Should private cars be banned from city centres entirely? One side argues bans cut pollution and accidents while freeing space for people; the other argues they punish commuters, shoppers and disabled drivers who have no fair alternative.
   
   2. Should congestion charges be the preferred tool instead of outright bans? Supporters say fees change behaviour flexibly and raise money for transit; opponents say they make city streets a luxury for the wealthy.
   
   3. Does removing cars from city centres help or hurt local businesses? One side claims pedestrian zones draw more foot traffic and spending; the other warns that customers who drive elsewhere take their money with them.
   
   4. Is it fair to ask city residents to give up car ownership for the sake of cleaner air? One side argues city living is a choice that comes with accepting public transport; the other argues freedom of movement is a basic right, not a lifestyle concession.
   
   5. Should emergency and delivery vehicles be the only cars allowed in city centres? Supporters say exceptions for services prove a car-free centre can still function; critics argue that once you allow some vehicles, the rule becomes a maze of permits and loopholes.

8. Claude Haiku 4.5

   Passed: Graded 4.3 of 5 on average (lowest 3).

   1. Should cities ban private cars from their centres entirely, or would this unfairly harm people who depend on vehicles for work and mobility? One side argues that bans reduce pollution and reclaim space for pedestrians; the other contends that they penalise workers and disabled people who have no alternative.
   
   2. Do the environmental benefits of car-free city zones outweigh the economic losses to local businesses that rely on customer parking? Supporters say cleaner air and foot traffic boost long-term prosperity; opponents say immediate closures will drive customers online and to out-of-town rivals.
   
   3. Is congestion pricing (charging drivers to enter city centres) a fair solution to traffic, or does it create a two-tier city where only the wealthy can afford to drive? One position holds it's the most efficient way to cut emissions while funding transit; the other sees it as a regressive tax on ordinary commuters.
   
   4. Should cities prioritize converting car lanes to cycle paths and bus lanes, even if it means longer journey times for remaining drivers? One view argues that faster, safer public transport will eventually shift people away from cars; the other warns that gridlock will worsen before it improves, harming delivery services and emergency response.
   
   5. Do historic city centres benefit or suffer when cars are replaced by pedestrian zones and public transport hubs? Advocates say walkable streets attract tourists, residents, and investment; critics argue that car-dependent shoppers will abandon them for malls with free parking.

   1. Should the city of Bellwick ban private cars from its centre to reduce air pollution? Supporters might argue that cleaner air would protect residents’ health; opponents might argue that the ban would make essential trips harder for people with limited transport options.
   
   2. Should drivers pay a congestion charge to enter the centre of Northbridge at rush hour? Supporters might say the fee would cut traffic and fund buses; opponents might say it would unfairly burden workers who cannot change their hours.
   
   3. Should shops on Market Street lose their on-street parking spaces to make room for a cycle lane? Supporters might argue that safer cycling would bring more customers over time; opponents might argue that shops could lose sales before that happens.
   
   4. Should delivery vans be allowed into the city centre only before 10 a.m.? Supporters might say the rule would make crowded streets safer; opponents might say it would leave restaurants and pharmacies struggling to receive urgent supplies.
   
   5. Should the city replace its central car park with housing and a public square? Supporters might argue that homes and open space serve more people; opponents might argue that losing the car park would make the centre less accessible to visitors and businesses.

10. GPT-6.1 Sol

    Passed: Graded 4.7 of 5 on average (lowest 4).

    1. Should Riverton ban private cars from its city centre while allowing buses, emergency vehicles and transport for disabled residents?
    Supporters might argue that cleaner air and safer streets justify the restrictions; opponents might argue that the ban would still disadvantage people who cannot easily walk, cycle or use public transport.
    
    2. Should drivers pay a congestion charge to enter Westbridge’s city centre if all the revenue funds cheaper bus fares?
    Supporters might argue that drivers should help pay for reducing congestion; opponents might argue that the charge unfairly burdens lower-income workers whose shifts begin before buses run.
    
    3. Should electric cars be exempt from a proposed ban on cars in Kingswell’s city centre?
    Supporters of an exemption might argue that it rewards cleaner transport; opponents might argue that electric cars still cause congestion, take up space and endanger pedestrians.
    
    4. Should Bellmarket replace half its city-centre parking spaces with wider pavements, trees and outdoor seating?
    Supporters might argue that more welcoming streets would attract shoppers and improve public health; opponents might argue that losing convenient parking would drive customers away from local businesses.
    
    5. Should delivery vehicles be allowed into Oldport’s car-free city centre only between midnight and 6 a.m.?
    Supporters might argue that overnight deliveries would keep daytime streets safe and shops stocked; opponents might argue that noise and night-shift demands would unfairly burden residents and delivery workers.

11. DeepSeek V4 Pro

    Passed: Graded 4.3 of 5 on average (lowest 3).

    1. Should private cars be banned entirely from city centres during daylight hours? One side argues a ban cuts pollution and reclaims streets for pedestrians and cyclists, while the other side argues it strangles small businesses that depend on drive-in customers and isolates residents with limited mobility.
    
    2. Should cities charge a congestion fee for every car entering the centre, with all revenue going to public transit? Proponents say pricing reduces gridlock and funds greener alternatives, but opponents say it is a regressive tax that punishes shift workers who have no reliable bus or train at night.
    
    3. Is it justified to remove on-street parking in city centres to create protected bike lanes and wider sidewalks? Supporters claim reallocated space improves road safety and boosts foot traffic for shops, while critics claim losing parking drives customers to suburban malls and makes errands harder for older drivers.
    
    4. Should emergency vehicles be the only motorized traffic allowed in a fully pedestrianized historic core? One side argues historic centres thrive without exhaust and noise, becoming safer tourist destinations, while the other side warns that delivery access, resident mobility, and waste collection become impossible logistics.
    
    5. Do low-emission zones that ban older diesel and petrol cars from city centres unfairly target lower-income drivers? Advocates say these zones are the fastest way to meet air-quality health targets and reduce child asthma rates, but opponents say they create a two-tier city where only the wealthy can afford newer compliant cars.

12. Kimi K3

    Passed: Graded 4.3 of 5 on average (lowest 4).

    1. Should private cars be banned entirely from city centres, with access limited to public transport, delivery vehicles and emergency services?
    For: cleaner air, safer streets for pedestrians and cyclists, and quieter, more pleasant public spaces. Against: harms disabled people, tradespeople and small businesses who depend on vehicles, and pushes congestion to surrounding neighbourhoods.
    
    2. Should drivers pay a daily congestion charge to enter the city centre, as London and Stockholm already require?
    For: the fee cuts traffic, funds public transport and makes polluters pay for the damage they cause. Against: it is a regressive tax that lets the wealthy drive freely while pricing out lower-income workers who have no realistic alternative.
    
    3. Should cities convert car parks and on-street parking spaces into housing, parks and outdoor cafés, even if it makes driving impractical?
    For: land in the centre is too valuable to store empty cars, and removing parking is the fastest way to change travel habits. Against: it punishes people before decent alternatives exist and devastates shops whose customers arrive by car.
    
    4. Should the shift to electric cars settle the debate, allowing cities to welcome vehicles back without guilt?
    For: electric cars produce no exhaust fumes, so banning them solves a problem that technology has already fixed. Against: they still cause congestion, road deaths, tyre-dust pollution and sprawl, so the case for limiting cars stands regardless of the engine.
    
    5. Should children be able to walk or cycle to school safely, and should that right override adults' convenience when designing city-centre streets?
    For: a city that is safe for an eight-year-old is safe for everyone, and protecting children justifies school streets, lower speed limits and car-free zones. Against: redesigning streets around children ignores the needs of commuters and businesses, and safety can be achieved with crossings and supervision instead of restrictions.

13. Mistral Large 4

    Passed: Graded 4.0 of 5 on average (lowest 3).

    1. Should municipal governments ban all private cars from city centres to create permanent pedestrian-only zones? One side argues this is essential to cut carbon emissions and eliminate traffic deaths, while the other contends it would bankrupt small shops and trap elderly or disabled residents who have no affordable alternative.
    
    2. Is it ethical to charge congestion fees high enough to price working-class drivers out of downtown areas? Advocates say the revenue funds better public transit and clears gridlock for emergency vehicles, but critics insist it creates a two-tier city where only the wealthy can access jobs and services in the urban core.
    
    3. Should historic city centres prioritize preserving their ancient street plans over accommodating modern vehicle traffic? Preservationists claim narrow medieval roads were never meant for cars and deserve protection as living heritage, whereas accessibility advocates argue residents deserve the same right to drive and park as people in suburban neighborhoods.
    
    4. Do electric vehicles make city centre car bans unnecessary, or should cities restrict all motorized traffic regardless of power source? Supporters of EVs argue they solve pollution and noise while keeping mobility for families and deliveries, but opponents counter that congestion and pedestrian danger remain deadly even with zero-emission engines.
    
    5. Should cities pedestrianize main streets only on weekends, or close them to cars every single day? Weekend-only advocates say this balances commerce and livability without crippling weekday commuters, while daily-closure proponents insist partial measures merely displace traffic to residential neighborhoods and fail to change car-dependent culture.

14. Claude Sonnet 5

    Passed: Graded 4.0 of 5 on average (lowest 4).

    1. Should city centres ban private cars entirely and rely on public transit, cycling, and walking? Supporters argue it would cut pollution, noise, and traffic deaths; opponents argue it would cripple small businesses, disabled residents, and anyone who can't afford to live near the core.
    
    2. Should residents of a city like Amsterdam or Bristol vote on congestion charges that price ordinary commuters out of driving downtown? Proponents say the fees fund transit and reduce gridlock; critics say it's a tax that punishes working-class drivers while wealthy residents pay it without blinking.
    
    3. Should delivery vans and rideshare cars be banned from historic city centres to protect cobblestone streets and pedestrian zones? One side argues that heritage and safety justify the restriction; the other argues that shops and elderly residents depend on those deliveries reaching their doors.
    
    4. Is converting a city's main shopping street, like Oxford Street in London, into a permanent pedestrian-only zone worth the loss of parking and drop-off access? Advocates claim foot traffic and outdoor dining will boost sales; shop owners counter that customers who drive will simply go elsewhere.
    
    5. Should emergency vehicle access requirements override calls to remove all car lanes from a city's downtown grid? Safety officials argue that wider car lanes save lives in fires and medical emergencies; urban planners argue that narrower streets slow traffic and make accidents rarer overall.

15. Claude Sonnet 5.5

    Passed: Graded 4.7 of 5 on average (lowest 4).

    1. Should the council of a mid-sized city like Leeds ban private cars from its centre entirely by 2030, even if it means some small shops lose the customers who drive in? One side might argue that clean air, safer streets and space for pedestrians will bring more people and more spending in the long run. The other side might argue that shoppers, older residents and disabled people depend on cars, and closing the centre could hollow out family-run businesses.
    
    2. Is it fair to charge every driver £15 a day to enter the city centre when a nurse finishing a night shift pays the same as a tourist in a rented sports car? One side might argue that a flat charge is simple, cuts congestion quickly and funds better buses. The other side might argue that it punishes low-paid workers with no alternative and that exemptions or income-based pricing are the only just approach.
    
    3. Should the multi-storey car park on Harbour Street be demolished and replaced with a public park, given that it is the only affordable parking near the hospital? One side might argue that green space improves health and that visitors should be pushed towards trams and park-and-ride. The other side might argue that patients, visitors and staff need reliable parking close by, and that removing it could cost people time when it matters most.
    
    4. Should self-driving electric taxis be the only vehicles allowed in city centres, replacing both private cars and human-driven cabs? One side might argue that a single fleet of clean, shared vehicles would reduce traffic, pollution and the need for parking. The other side might argue that it would end thousands of cab drivers' livelihoods, hand control of city transport to a few companies and risk safety failures the public never agreed to.
    
    5. Is a car-free Sunday in the city centre a meaningful step towards change or just a symbolic gesture that inconveniences residents for one day a week? One side might argue that it lets people experience a calmer city, builds public support for larger reforms and gives local markets and cafés a boost. The other side might argue that it changes little about everyday traffic, shifts congestion to surrounding streets and blocks people who rely on Sunday travel for work, worship or family visits.

    Passed: Graded 4.7 of 5 on average (lowest 4).

    1. Should Bath close its historic centre to private cars on weekdays, even if hotel guests must drag luggage from a park-and-ride? One side says Roman streets cannot survive modern traffic without losing what visitors come to see; the other says a car-free centre shuts out older guests and local trades with no other way in.
    2. Is a congestion charge on cars entering Manchester’s centre a fair price for cleaner air, or a tax on people who cannot live near their jobs? Drivers should pay for the delay and fumes they impose, say supporters; opponents say it hits shift workers and carers while wealthier residents already ride the tram.
    3. Should a city demolish the multi-storey car park on Queen Street and build flats there, even if Saturday shoppers then have nowhere to leave a car? Advocates argue every bay kept for cars is a home not built; retailers warn that without parking the high street empties and the rates that fund the city go with it.
    4. Ought a car ban in a city centre stop at emergency vehicles, or should taxis and blue-badge holders face the same barriers as everyone else? One side says every exception becomes a loophole until the ban means nothing; the other says a rule that blocks a wheelchair user or a night-shift nurse is not a safety policy.
    5. Would letting only electric cars into city centres clean the air, or merely swap one queue for another? Proponents say tailpipe fumes are the harm worth targeting; critics say electric cars still take road space, still injure people on foot, and still crowd buses off the street.

    1. Should Bristol ban private cars from its city centre if buses and trams cannot yet meet everyone’s needs?
    For: a ban could cut pollution and make streets safer; against: introducing it too soon could exclude people who depend on cars for work, care or essential journeys.
    
    2. Should Manchester charge drivers to enter the city centre, with all revenue reserved for cheaper public transport?
    For: drivers would help fund alternatives while reducing congestion; against: wealthy motorists could simply pay while lower-income workers face difficult choices.
    
    3. Should York replace half its city-centre car-parking spaces with trees, benches and outdoor trading areas?
    For: more welcoming streets could benefit residents and attract shoppers; against: losing parking could deter customers and threaten businesses that rely on visitors arriving by car.
    
    4. Should Birmingham allow delivery cars into its city centre only before 8 a.m., even if this makes deliveries more expensive?
    For: restricting delivery traffic could make busy daytime streets safer and less congested; against: higher costs and early arrivals could hurt small businesses and disturb residents’ sleep.
    
    5. Should a citizens’ assembly selected by lottery have the final say on whether Oxford’s city centre becomes car-free?
    For: a representative group could weigh competing needs more carefully than a polarised public campaign; against: a small, unelected assembly should not control a decision affecting thousands of people’s livelihoods and daily journeys.

    Passed: Graded 5.0 of 5 on average (lowest 5).

    1. Should a mid-sized city like Leeds ban all private cars from its centre within ten years, allowing only buses, taxis, bikes and emergency vehicles? Supporters might argue it would cut pollution and road deaths and give streets back to people, while opponents might say it punishes commuters from towns with poor public transport and could empty the centre of shoppers.
    
    2. Is a daily congestion charge on drivers entering a city centre a fair way to fund public transport, or is it a tax that hits the poorest hardest? One side might argue that drivers should pay for the space, noise and fumes they impose on everyone else, while the other might argue that wealthy drivers will simply pay while shift workers and small traders are priced off the roads.
    
    3. When a city council removes 300 parking spaces on a busy high street to build a protected cycle lane, should the shop owners who say their takings will fall have the power to block it? Those for the veto might argue that local businesses know their customers and carry the financial risk, while those against might argue that studies often show cyclists and pedestrians spend more over time and that one street's traders shouldn't decide safety for a whole city.
    
    4. Should disabled drivers and their carers be exempt from every car restriction in a city centre, even if that means hundreds of extra vehicles in a pedestrian zone? One side might argue that access to shops, doctors and jobs is a basic right that no green policy should override, while the other might argue that blanket exemptions invite abuse and that better accessible public transport would serve disabled people more fairly.
    
    5. If self-driving electric cars become safe and quiet, does the case for keeping cars out of city centres disappear? Some might argue that the main harms of cars, such as crashes, noise and emissions, would be solved and cities should welcome them back, while others might argue that even perfect robot cars still take up huge amounts of space that could be parks, homes and pavements.

19. Claude Fable 5.1

    Passed: Graded 4.7 of 5 on average (lowest 4).

    1. Should Bristol ban all private cars from its historic centre by 2030? One side argues that cleaner air, safer streets and a revived high street outweigh the disruption; the other argues that disabled residents, tradespeople and outlying suburbs would be cut off, and that a ban punishes those who can least afford to live centrally.
    
    2. Should a city like Manchester charge drivers a daily congestion fee to enter its core, as London does? Supporters say it is the fairest way to make drivers pay for the space, noise and pollution they impose on everyone else; opponents say it is a regressive tax that clears the roads for the wealthy and pushes low-paid shift workers onto unreliable night buses.
    
    3. Should the multi-storey car park on Castle Street be demolished and replaced with housing? One side contends that a city facing a housing shortage cannot justify five floors of empty concrete for cars that sit idle 95 per cent of the time; the other contends that without parking, the theatre, the market and the independent shops that depend on out-of-town visitors will close within two years.
    
    4. Should cities prioritise electric cars, or aim to remove cars from their centres altogether? Advocates for electrification argue it solves the pollution problem without forcing people to give up the freedom and convenience of driving; advocates for removal argue that an electric traffic jam is still a traffic jam, and that tyre dust, road danger and lost public space have nothing to do with the exhaust pipe.
    
    5. Should a city council overrule a referendum in which residents voted 58 per cent to keep cars in the town centre of Lewes? One side argues that elected leaders have a duty to act on evidence about air quality and road deaths even when it is unpopular; the other argues that a council that ignores a clear public vote forfeits the trust it will need for every future change.
