I'd much rather just have BEVs with a standardized external range extender interface similar to how trailer light/brake connectors work, accompanying a trailer hitch. When I need to do a long trip I'll just have the power pack thrown on the back at the neighborhood depot next to the propane tanks at the gas station. It can have a fossil fuel powered generator, or just be batteries, I don't care. What I do care about is not having to cart around an ICE 100% of the time for the sake of trips I do <=10% of the time. Maintaining ICE garbage is not something I see in my future, and I'm an experienced graybeard grease monkey.
