Recently a fairly high profile incident of a Model S apparently taking a joyride all on its own, and then crashing into the back of a trailer, has hit the mainstream media (full details/video here).

A Utah Model S owner says that after he exited his car (and gave a little demo of how it operated to an onlooker), he entered a local business to go about his day...only to find upon his return that his Tesla had crashed into the back of a truck trailer.

The owner says the car acted on its own, Tesla logs show "the incident occurred as a result of the driver not being properly attentive to the vehicle’s surroundings while using the Summon feature or maintaining responsibility for safely controlling the vehicle at all times.”

Basically a "he said/Tesla says" scenario has broken out, with no reasonable conclusion or "how it actually happened" verdict on the horizon...until now.  

Tesla YouTube celebrity Kman (KmanAuto - subscribe here) has a pretty good idea how it happened, and passed the above video along to us on how he thinks it all went down, as well as some commentary on the incident and Tesla's credibility on the matter.

Thanks to Kman!
