The EV/road tax has been a talking point for years. Pretty much since Tesla cars started making a splash, but it's only since EV sales have really taken off that some states are trying to do something about it. It's a valid point. States use gas taxes to maintain the roads and that work isn't getting any cheaper.
Some states have considered a $/mile use fee, collected as part of registration. PA could somewhat easily do that because of the annual inspection process that records the odometer reading by a 3rd party.
There are no great solutions since any sort of use-tax tends to put more of a burden on those who can least afford it. A big advantage of gas taxes is the "death by 1000 cuts" approach as you are paying a bit every time you buy gas. A registration tax/fee on someone who drives a lot for work could turn into a pretty big bill they might not have budgeted for.
