Oh I agree that semi’s are much heavier. That is obvious.
But they are much heavier than the average car and the roads are not at all designed for half of our cars to be that heavy. States are already noticing that their roads are getting extra ripped up by the 5% or so we have. Also, barriers much more easily breached (as they are by semi’s as well).
A Tesla S and a Ford Explorer weight the same and both sit on 20 inch alloy wheels with nearly identical tire patch foot prints. Look at the post above ^^^^

This has more to do with the switch from 4 door sedans in the 3500lb class to Trucks and SUVs in the 4500 to 6000lb classes. Even smaller SUVs are 4000+ lbs now and those are what most of the newer vehicles are now trucks and SUV out sell cars three to one in the USA
