I'm a startup guy in silicon valley and I've always wondered about this, so I figured I'd go to the source and ask Tesla owners: If you run out of charge on the side of the road, how much would you pay to have an "electric tow truck" show up, that was basically a Supercharger on wheels and could provide you some charge, for some amount of money? Specifically, I'm wondering: - How much minimum range would it have to provide you to be worth it? - How much would you pay? - How fast would it need to charge your car? - How long would you be willing to wait for it to arrive? Seems like a totally do-able idea from a technical perspective. Mostly just wondering why I've never seen anyone do it yet.
