Because if you live in an apartment your only option for charging is to go to a charging location. You can’t just plug it in overnight.
Which I can see as a big hurdle for a lot of people.
I charged my EV overnight from an overhead garage door power socket in my apartment for years before I moved out. Never even needed public charging. Many people just don’t realize you can charge from a normal household outlet
I’ve never had an apartment with a garage. At minimum I’d have needed a 100 ft extension cord. Probably longer, which means it’d have to be thicker. Which means more expensive.
Near all apartments around me have exclusively open-air parking, so this isn’t a viable solution for many. It’s not that the available power is inadequate, it’s non-existent.
