Yeah, I've thought about this too, but real use cases would be rare and maybe somewhere along highways for long trips, but you'd need a lot of stations in hard to predict locations to make it something people could use. Most of the time a simple recharge at night at the domicile would suffice. Add trying to get battery form factors standardized when companies can't even agree on a universal charger and challenges to upgrading vehicle frames and design if such a standard was ever adopted and it just seems unsustainable.
