Electric cars aren’t really giving them a run for their money. Road damage goes as the 4th power of axle weight [1]
A fully loaded semi is 80,000 lbs and has 5 axles so 16,000 lbs/axle.
A Tesla model S weighs 4500 lbs and has 2 axles, so 2250 lbs/axle.
16000/2250 = 7.1
7.1^4 = 2541
So the truck is doing 2500x the damage of the Tesla. Esentially all road damage is done by heavy trucks which is why semis have to pull over and get weighed periodically to make sure they’re under the limit, but cars never do.
