Charging hybrids halve as much when they can run on electricity most of the time seems less than ideal.

Also most usage based wear and tear comes from trucks anyway. Meaning charging light vehicles isn't nessecary.

You could just move the gas tax to a vehicle tax for road existence and upkeep to heavy vehicles usage.

Conservatives do that. It’s unfortunate.

Why don't they just tax by amount of electricity charged. Prolly naive, but it's similar to the tax on gas and solves exactly the problem that is brought up with flat payments per car per year.
