Not sure. In the comment I replied to, they mentioned that EV is good 95% of the time. In that case, renting a car, like once a month, for a long range tip would make sense imo. Better yet, public transport, then rent an EV there.
Or just get a PHEV. And then you only need 1/3 of the batteries in your car, and you don't have to deal with rentals. Does it really make sense to have 300 miles worth of batteries that you haul around in your car when 90% of your trips are less than 100 miles?
