People renting cars for either business trips or pleasure/vacation do not have time for 1/2 hour to an hour of charging, when 5 minutes at a gas pump could have gotten them the same effect with an ICE car. This is not that hard. Time is at a premium on these trips, and EVs do not respect that.
SIL rented one for business last year and had a bad experience. She told all her business associates and friends about it. It doesn't take long for word to get around..
