i'm with the fuel crowd.
it's the fairest way to ensure that not only are people paying in accordance to the miles they do, but also the car they choose to drive.
for example the new model v8 mustang that sits in the owners garage save for a couple of trips in summer is not an emissions problem, but the 2ltdi golf driven by the salesman doing 100k a year is very much a problem.
i remember clarkson of all people arguing about doing it to f1, scrap a lot of the various engine regs and simply put a heavy fuel limit on the cars, if the tech means cars start getting too fast to be safe then slash the fuel limit again.
You don't seem to be understanding the issue. People aren't buying fuel going forward with growing EV use. Fuel is already massively taxed.
