Batteries and motors have been around longer than the ICE but ICEs won for a reason. Sure electrical motor and battery tech has come a long way but so has the ICE and the efficiency from things like VVT MDS variable runner intakes, stratified charges, turbos, 8-10 speed or even more transmissions have all helped improve the efficiency of ICE cars dramatically.
I'm really not an electric car proponent, but even after all you said is absolutely true, electric has thermal efficiency in spades over ICE's. Nothing I know of is ever going to overcome that. Long trips in electric cars are going to be longer than ICE's. A lot of people seem to be wiling to bear this burden. I don't think it'll be long before the novelty wears off and they'll want an ICE powered vehicle for trips, unless they go airlines? FWIW, I hope to NEVER again enter a winged greyhound
