We’ve been a two BEV family for three years with no ICE backup. Even though our cars are shorter range (My BMW i3s and wife’s Mini-e) we go from Surrey to Northumberland twice a year using public charging.
It’s honestly fine. Yes, it’s more inconvenient to stop more times to charge, but I’ll take that for the rest of the year when our cars are charged overnight and I don’t have to visit fuel stations and get diesel all over my wheelchair wheels (that stuff is horrible).
