I would say that is only because people fictionally think they need a 300+ mile range. My i-MiEV goes 40 miles now after 8 years 65 miles new and rarely will it not go where I need to go. I have a Tesla now and it’s so much nicer I drive it most of the time. But before COVID I drive the Mitsubishi everyday to work. I love that car and while the range cuts it close sometimes I think With 100 mile range I would have Zero issues.
