Saw a video review of Model S and the reviewer stated (and demonstrated) that when he was backing up and twisted around to look over his shoulder, his position in the seat changed and the car jerked to a stop. (About 4:50 mark here).
This does not seem like a very safe thing for the car to do, and I'm wondering if it was some sort of defect on the test vehicle. It seems to me that if the car is in Drive or Reverse, and is moving, the seat sensor should be disabled. A normal ICE will not throw itself into Park like that. I sometimes adjust my seating position by pressing my arms down on the armrests and sliding my butt into a more comfortable position, and I certainly wouldn't want the car suddenly jerking to a stop on the freeway.
Wondering if any current Model S owners have seen this behavior?
