Semi truck driver. I work for one of the largest nation wide trucking companies in America. We have these in all our trucks, but only one forward facing camera. The driver is not visible. I have been flagged a few times for following too close, after a car cuts in front and I didn't slow down and back off soon enough. In our case, the truck radar detects the following distance, and you get an audible alarm. If you back off soon enough, no harm no foul. There are other sensors in the truck that detect hard braking, hard turns, speeding, etc. If your truck rats you out, your boss reviews the telemetry and the video, then has a coaching call with you. We are told that the camera only records fifteen seconds before and after an incident. In my case, I appreciated the recording and coaching, because I then had to think about how to prevent further incidents. My solution was to slow down a couple mph in crowded situations, which works because people who cut in front of you are a little more likely to be automatically pulling away. Not weighing in on the appropriateness of Amazon's solution. But the yawning thing would drive me nuts. We all have yawning bouts.
