此外，对汽车等柴油车的需求价格缺乏弹性。这意味着当价格变化时，需求变化不大。在这种情况下，即使政府对进入曼彻斯特的柴油车收取费用，人们仍然会带着他们的汽车进入曼彻斯特，而不是解决污染或拥堵问题，而是继续增加人们需要支付的费用。如果需求是价格无弹性的，政府可能试图通过收取过高的价格来迫使消费减少，这意味着许多穷人可能无法负担额外的成本，而富人将不受不平等加剧的影响。其他一些城市已经采取了这些规定，试图解决交通拥堵和污染问题。“伦敦实施空气质量收费已经有一段时间了。它的“低排放区”已经覆盖了大伦敦的大部分地区，对污染最严重的卡车、大篷车、大型货车、巴士和长途汽车每天收费100至200英镑。但是从明年4月一个新的24小时“超低排放区”也将介绍在伦敦中心涵盖所有类D车辆从那时任何人都更污染柴油汽车——通常这些注册在2015年9月——将不得不支付£12.50之前一天开车到首都的中心。然而，对伦敦而言，引入清洁空气区要比大曼彻斯特容易得多，这要归功于15年前引入的基础摄像基础设施，它们负责运营工作日的拥堵费。

Also, the demand for diesel vehicles such as cars are price inelastic. This means that when the price changes, the demand does not change as much. In this situation, even if the government charge diesel vehicles to enter Manchester, people will still enter Manchester with their cars not resolving the pollution or congestion problem but still increasing the amount people would have to pay. If demand is price inelastic, the government may try to force the consumption to decrease by charging prices that are too high meaning many poor people may not be able to afford the extra cost, while the rich will be unaffected increasing inequality.There are other cities that have already undertaken these regulations trying to tackle the problems of congestion and pollution. “London has had air quality charging in place for some time. Its ‘low emissions zones’ already cover most of Greater London and charge between £100 and £200 a day on the most polluting lorries, motor caravans, large vans, buses and coaches. However from next April a new round-the-clock ‘ultra-low emissions zone’ will also be introduced in central London to cover all Class D vehicles From that point anyone with a more polluting diesel car – generally those registered before September 2015 – will have to pay £12.50 a day to drive into the centre of the capital. The introduction of clean air zones has been considerably easier for London than it would be for Greater Manchester, however, thanks to the underlying camera infrastructure brought in 15 years ago to operate its weekday congestion charge.
