States used to have per-axle weight taxes for trucks for this very reason. It was part of how this country paid for the interstates in the first place. You can still pass many of the old weight stations on the interstates. It's still a surprise more states aren't turning the lights back on them and/or building new ones. I feel like the same could be applied to EV registration taxes attempting to make up for gas taxes: I think they should be charged on a scale by per-axle vehicle weight. It might help incentivize smaller cars again.
