TLDR paved roads are generally designed to handle large trucks and construction equipment. On such roads passenger vehicles (even heavy electric vehicles) have a negligible impact on pavement life.
The difference in road wear between a 2k lbs. vehicle and an 8k lbs vehicle is too small to matter.
I guess it'll be interesting when we are trying to support electric medium duty or heavier trucks, like WA is trying to do. Guess they'll be subject to Class 7 & 8 weight anyways, because if you try to make a currently-medium-duty truck into an EV it's way over the limit.
I mostly just have doubts about our current revenue model scaling for it (since it's heavily reliant upon gas tax and the truck weight $$ amounts don't match up), and the general lack of lighter EVs in the US. Something will have to change there
I'd be totally happy in the city with a 2-2500 lbs BYD Seagull or whatever. But that vehicle doesn't exist in the US.
A vehicle the size of a Seagull is practically a non-starter in the US in terms of mass-market appeal. Most US consumers think of the Chevy Bolt as too small of a car, and that's like 20" longer than a Seagull.
