I want to be able to drive a _large_ vehicle with 4 people, 2 dogs, and "back woods" camping gear on open highway for 24hours with out stopping. When I do stop it needs to be less than 30 minutes, and cost similar price to a diesel truck that gets 20mpg. I'm not expecting much by 2035, but we'll see.
