Local delivery and towing are perfect. The infrastructure for mere mortals is a completely different matter.
My neighbor’s Tesla has been down for months and months with a main battery problem. A Tesla tech came by in a reliable Ford Van to fix it. It’s still in the driveway with part of the front fascia duct taped up from an accident.
Under the dash there is a 12v regular car battery. They don’t like to sit unused. You have to take about 10 trim pieces in the frunk out to access it. I watched him do it. Pretty funny.
I don't know about Tesla. But in the Nissan Leaf and some other makes, the 12v regular battery is periodically recharged by the EV batteries, even when the car is sitting around unused. Seems that should be regular procedure for any EV.
