Perhaps what sticks in the throat most is the blanket ban on all bikes made before 2007. Those who ride a barely polluting 50cc scooter can feel particularly aggrieved, while owners of bigger bikes will still be hard done by. Start to compare this to cars, which have to comply with Euro 4 standards to be exempt from the ULEZ fee, and it comes to light that a small 50cc scooter made in 2006 (producing under 50 CO2 g/km, producing close to 150mpg) will have to pay the charge, but a newer sports car – running a 5.0-litre V8, good for 15mpg – is exempt. Emissions aside, bikes cut city traffic, cars contribute towards it. How can we even begin to see this as fair?
