Presumably, tow trucks will eventually be equipped with generators or battery packs/supercapacitors that can dump 50 miles or so of charge into a stranded EV. But it will be a while. For now, you need to call for a tow. Maybe the tow truck can just pull you along for a while until the regenerative system gets some juice back in the batteries? But I thought I read that EVs had to be towed on a flatbed not on their wheels.
