The problem is, most these spots are not legally marked for electric vehicles only. Either the state doesn’t have clear laws on how to mark them, or Tesla hasn’t done that. I know in Washington state there are very specific laws on signage that needs to be posted, the color of paint used for the spot, etc for it to be legally electric only. I’ve never seen a Tesla Supercharger that follows those rules. Presumably because the business owner isn’t willing to legally block those spots from other people. I’m not sure you could actually have a tow truck tow someone like that, unless the business owner called and then he might be responsible for fees or damages since the car wasn’t actually legally doing anything wrong.
