I know it's human nature to try to figure things out and contemplate scenarios but if someone asked me what I think is most likely, I'm going with the simplest explanation until I hear official results of a proper investigation. Someone said it earlier. What do you do when showing off your Tesla? You: (1) Demonstrate acceleration and (2) Demonstrate autopilot. To me, the most likely scenario is (1) going wrong and ending up in a tree. Without any additional evidence, movie plots like a 10 second sprint to turn on AP and the driver diving to the back seat, or two wives plotting to kill their husbands are just that: movie plots.
