One semi-truck does the damage of over 200 Hummer EVs. As long as semis are allowed on highways, I think the effect you're describing will be negligible, especially since the really heavy EVs like that are expensive luxury ones, and the mass-market ones are all way lighter.

200? Did you pull that number out of a hat?

The hummer EV is around 9100 lbs.

If we assume the higher end of GVWR for a tractor trailer at 80,000 that’s 8.8 hummer EVs.

Tractor trailers are also typically size limited not weight limited for their loads, which would bring down the ratio much further.

Lastly having the weight distributed to many more tires (typically 18) instead of 4 must ease the load on the pavement, no?

Damage to roads is proportional to the 4th power of axle weight, which is about 4500 pounds for the Hummer EV and about 17000 pounds for a semi, and (17000/4500)^4 is a little over 200.
