It always amazes me how people can make a quick judgement, provide no evidence to support it, and then the media just rolls with it and ignores all evidence to the contrary. I'm speaking of the people who made the claim that they were sure there was no one in the driver's seat at the time of the crash and the media; not people here. Short of some ironclad evidence we may not be aware of... like maybe the driver's dentures being embedded in the BACK of one of the front seats from impact, I ask you, which of these would be more likely given the circumstances?
1: Owner takes someone on a test drive, decides to show off acceleration, starts in the cul-de-sac, and performs something akin to a 0-60 run, then loses control when he can't make the bend in the road. After striking the tree (one firefighter even said the car was wedged between two trees), the driver's door won't open so the driver checks other doors and ends up in the back seat trying to get out a back door before being overcome with smoke and/or fire.
2: Owner wants to show off autopilot so he starts at the end of the cul-de-sac and guns the throttle to get the car up to excessive speed within 300 feet. Since a Model S should be able to negotiate that curve at 50 MPH, let's say the minimum here is 60 MPH. Assuming a constant acceleration 0-60, getting to 60 by 300 ft takes 6.8 seconds. Let's say 7 seconds to be generous. So the driver guns the throttle, sets AP (or tries to), and then DIVES through the gap between the two front seats to get into the back within 7 seconds (with maybe 1.5 more seconds from that point to reach the tree). Then the car crashes into a tree with the driver in the back.
