I recently bought a used model 3 and Tesla mobile service was great. Had a broken trim clip and they came and fixed it under warranty in less than 15 minutes, no questions asked. That’s my only data point so far but compared to similar issues with ice cars it’s much better.

My understanding is that it’s one plug per spot and not spaced so that two spots could utilize one plug. That would have been a good solution for maximizing use of one station though.
