Here is another wrinkle in the fatal Tesla crash I mentioned earlier. The driver might have been watching a movie on a portable DVD player. Emphasis on "might". A DVD player was found in the car but eyewitness account differ as to whether it was playing or not. It is still not determined if the it was operating and, if so, whether the driver was watching it.
The Tesla "Autopilot" mode is semi-autonomous. It is not designed to replace the driver but rather to assist him. Apparently, Some Tesla drivers just do not get this!
This may be just be a case of advanced technology meeting an irresponsible person.
