Now that a lot of parking lots aren't so busy I've been getting experience with the Summon feature. There was only 1 car between me and my Model 3. Good thing I was watching closely because my car, clearly from the attached photo, had no intentions of stopping before impact (hmmm...would it know to stop then?). Unbeknownst to me at the time, but there was a driver and a passenger having lunch in the front seat of the vehicle I almost hit. Surprisingly, they didn't even seem to notice.
