With a used gas car you can repair an engine but not an electric battery powered one. You would wonder if that electric car will explode in flames just sitting there in your garage or while driving. Bad enough worry when brand new!
Well, in EVs defense (and I can't believe I'm doing so) the motors on an EV are stone simple and are unlikely to ever need repair. It's the batteries. There is just no way to pack enough power into current battery designs in a way that is efficient, safe, and dependable.
Maybe one day when they discover Unobtanium batteries and have nuke plants in every metropolitan area, they'll start to make a little bit of sense. That or Mr. Fusion.
