Recording mileage isn't that difficult, though there is the possibility of increased odometer fraud. Why count speed in the formula though? In addition to the difficulties and privacy implications of monitoring it, the worst damage to roads from heavy vehicles happens in front of traffic lights where they sit in one place for a while, then apply large forces to the road to get moving again.WetEV wrote: ↑Wed Nov 06, 2019 8:04 amA fair tax would be based on the wear and damage a vehicle does to the roads.
A fair tax would be something like axle weight cubed times number of axles times mileage times speed squared.
Yet recording mileage isn't realistic. Recording speed less so.
Yes, EVs should pay somewhat more than gas cars. Trucks and buses should pay most of the tax, as they do most of the wear and damage.
Axle weight should be not not to the third power, but to the fourth power.
Speed matters, but low speed stopping/acceleration matters more.
Things like type of suspension matter as well.
Your challenge got be doing some reading. Such as this:
