Under such a system the attempt is made to make the purchase and

of any vehicle very accurately match the full costs to society of such
purchase and use.

and that isn't easy. For example, a lot of people talk about
zero emissions vehicles which leads to the soundbite of
those cars really being pollute-elsewhere vehicles. And
which costs society more, the car powered by oil, the car
powered by electricity from nukes, or the car powered by
electricity from oil/gas/coal? Don't forget the decommissioning
of the nuke and the waste, but don't forget the cost of
mining and transporting the oil/coal/gas. etc etc etc.
