How will states pay for roads when gas taxes evaporate?

Probably not, road damage is mostly from heavy duty vehicles (think semi trucks) or weather. See: https://www.insidescience.org/news/how-much-damage-do-heavy-.... A few x heavier car will damage them more, but probably still trivially compared to heavy duty vehicles.

Taxing the trucks hauling around freight containers? Their vehicles were always the ones tearing up the roads the most anyways, because they were heavier. Now electric cars are heavier and giving them a run for their money, but still.

Companies opt to move their stuff on the road instead of by train, even with financial incentives to use trains, because they don't want to have to wait for their materials to be loaded onto the train. Right now the roads are too cheap for corporations not to take advantage. If they are already willing to pay the premium for faster transit, why not milk them a little harder?

In my midwest state, yearly registration is an extra $200 for ev, $100 for hybrid.

You're downvoted for apparent irrelevance even though you're absolutely right. It's a shame that those of us who dislike car-centric design have no affordable options in the US.

Without a hint of irony, Musk likes to talk about engineers optimizing solutions to a problem that shouldn't exist. An EV is still a car, and still contributes to the impoverishment of our lives. Cars shed brake and tire dust. They necessitate huge scars across our cities, removing double-digit percentages of land from productive use with their 6-lane roads, and massive parking lots and structures, and ruin much of the rest of the land with proximity to noise and particulate pollution. They make (or made) suburbs economical, contributing to increasing loneliness and isolation, as well as raising the financial bar for participating in society. They've ruined what makes cities great, and without giving us anything in return except huge money and time sinks.

Not much? EVs have better weight distribution and axle loads are similar to the front axle of an ICE car.

The road wear goes up to the third power of weight so you really should be looking at semis for road wear.
