Perhaps DMV.org could fill this role. The home page has tabs for each of these content areas you list. This website was founded by a guy who drives a Model S and invested in Tesla very early on. I had been unaware of the site until I met the founder over breakfast. Every millennial I have asked since (East Coast and West Coast) has said things like, “DMV.org is Wikipedia for anything to do with my car: registration, insurance, anything” (that was my son). DMV.org has 40 full-time people researching state-by-state regs and coding. The founder explained to me his plans to increase the EV content.-- A huge number of problems would be solved if Tesla hired someone to look up the laws of each state regarding registration / insurance / financing / etc. etc., and make it into a little handbook, and keep it updated when new laws were passed, and hand that handbook out to all the delivery staff for reference.
I no longer have a vehicle and had been unaware of the site. Running a few searches, they cover a range of EV-related state-by-state info.
