That’s really, really reaching. An ICE Camry weighs 3500lbs, a Model 3 weighs 4000lbs. You’re not even right.

I need to check again, but from my understanding the damage is exponential based on the vehicle weight, but also that real road damage is functionally nothing until you get to very large heavy vehicles

(4000/3500)^4 = 1.70 so that 70% more road damage with a fleet of EVs. I don't know how high Vehicle Registration is in your state, and Fuel Tax, but it does add up to a surprising amount that mostly goes into rebuilding highway infrastructure. So it does need to be accounted for. Our transportation highway network is a system. ]

You’re assuming that most road damage comes from passenger cars. In fact most road damage comes from large semis weighing 20,000+ pounds. The worst roads are almost always freight corrridors

I was wrong the Model 3 also weighs 3500lbs. With your thinking we shouldn’t have any trucks or pickups on the road. The Ford F-150 is the most selling vehicle of all time and it’s massive.

The other thing is the weight penalty for EV's vs ICE's is shrinking as battery energy density improves. You'd probably get parity if energy density improved by 50%.

No, I checked again, the standard Tesla model 3 is already at weight parity with a Camry.
