I heard this from someone who was at the factory: cannot verify veracity Tesla reviewed logs of the test drives. One of the cars was clocked as going at 120 mph. A model S actually got into an accident. The customer claimed that the 'throttle misbehaved'. Tesla looked up the logs and told the customer that 'you had pressed the throttle and the brake at the SAME time for longer than 3 seconds, so we automatically disengaged the throttle. That is why your speed was only 15 mph when the incident took place and not 55 mph'. How does liability insurance work for the test drives? I assume Tesla covers it.
