I think once the technology is dialed in the wrapper around it can change currently the emphasis is on aerodynamics and how do. We achieve longer range. Once battery advances allow plus 500 mile range in all conditions then that's when Ev's hit stride in the states. But if your looking at it that when will it happen it already is in other countries so the race to the solid state finish line is on and big oil is enjoying their last ride and I'm sure it will be fruitful for those involved. But as to my experience with heating cooling and long trips it's another great experience meaning it makes you think and is that ever bad. My trip to Florida from New Jersey 18 hrs ice 350 in gas. EV 20hrs and 165 in charging and no wife because she now flys because she now has an excuse it's longer but that's a godsend me and Fido have a pleasant drive that alone is worth getting an EV. But to me let's throw the football to the next generation and enjoy the ride and just maybe be amazed.
