I suspect that the sonic sensors might have trouble detecting anything that is "too close". They probably send out a sonic "chirp" and listen for a response. Sound traveling about one foot per millisecond (ms), a perpendicular hard surface 5 feet away would echo back in about 10 ms. So far, no problem in normal circumstances.
There might be a problem if the echo returns too quickly after the "chirp" is started, since the echo might not be heard while the sensor is still making, or recovering from making, the "chirp". The sensor might think that nothing is there, with ... not good consequences.
I do not know how the Tesla's sensors work, but they MIGHT have this "too close" problem.
Why your car moved is a different issue, perhaps the fob and the assb-est-ist?
