The preliminary results of that NTSB investigation have been released, and they are concerning. Notably, the data from the crashed vehicle shows that the driver had his hands on the wheel three times in the 60 seconds leading up to the crash, but for the last six seconds, his hands were not on the wheel. Also interesting is that Autopilot had been following a vehicle at 65 miles per hour and then began to steer itself left toward a crash attenuator and accelerated to just over 70 mph.

The NTSB findings indicate that Autopilot steered the vehicle towards the crash attenuator and accelerated.
