So 500 mile trip can be done. Just a question of whether someone would want to deal with the inconveniences you listed.
Worst case scenario: You need to leave town on a moment's notice and you don't know how long you'll be away. Then I'd think a BEV at this point would not be my preferred choice vs. an ICE vehicle. Too many unknowns in your trip plan.
But really, how often does this happen for anyone? BEV is good for, like you said, avg 30 mile trips. I wouldn't give up the instant torque, zero emissions, etc. for the peace of mind that I'd have a car ready that would help me run from the law as a fugitive one day
