I lived in California for 11 years and had out of state plates for the entire time, legally. Not even weird. There’s so many ways and reasons that you can live in a state, or work in a state full time and legally be able to register your vehicle in another state.
Registration fees are simply not the way. There HAS to be some kind of equitable use tax or fee.
A gas tax seems pretty dang effective to me. It doesn’t capture electric vehicles correctly, but honestly right now we WANT to encourage the use of electric vehicles so I don’t think it’s quite time to flip the table and try to implement a new system.
We’re still in a transition period and we need to do everything possible to discourage gas powered vehicles, and taxing the shit out of consumer unleaded and diesel is an awesome way to do it. Honestly, anyone suggesting otherwise raises my hackles. There’s not that many electric vehicles on the road in the USA, even in urban California.
I’m suspicious of any new laws that would reduce the costs of fossil fueled vehicles while offloading more costs to electric ones.
I was skeptical about your claims about weight having such an outsized effect, but it looks like there’s merit. Seems like it’s a super complex area of study, and we have observational data that gives us rules of thumb that transportation and pavement engineers use to estimate pavement damages over time. Thanks for bringing that up, I’ve learned stuff today!
I still don’t think it’s as simple as taxing trucks though. Registration is part of the solution, but so is gas/sales/tire/oil disposal taxes, weigh stations, tolls, parking fines, crush charges, etc etc etc.
There’s a lot of things that would need to happen in order to effectively capture and recompense road damage in California, if that were a goal of the state. Unfortunately I have very little faith that California can do it - for all the good things about California, effective governance or municipal problem solving is not really on the list from what I’ve seen. It’s a shame, because they really have the resources, it’s just all such a mess.
