I've ridden in a Tesla a number of times - it's a great car and I've not met an owner yet who complains about the range. I get the concern about hurricane evacuations but the probability of a direct hit requiring a mandatory evacuation in TV is low. EV owners of any brand could always leave "early" if that was of significant concern. If you like/want a Tesla - then I hope you buy one. They are awesome cars.
