Not that many have driver facing cameras.
Swift did for a year or so. They lost so many drivers over it, and the cameras did not usually help them in any case. They are forward facing only now.
Although, the forward facing cameras can also ‘see’ what you are doing sometimes.
One of the training videos I just watched was about a driver that died, which was attributed to distracted driving.
In the video they showed video clips during the 30 days prior to the fatal crash.
In each clip the reflection on the windshield showed a tablet computer, sometimes with movies playing.
The driver hit another big rig that was stopped on the shoulder. His truck was burnt to a crisp, with him inside.
(Yet another reason to NEVER pull off to the side unless you have no other choice. The parked driver survived, but at what cost to him and his truck?)
These days it isn’t the driver facing camera you need to be concerned about so much as it is all the other forward facing stuff.
Those things can detect your following distance, your speed and the posted speed limits, even if you roll through a stop sign without coming to a complete stop, cornering and braking forces.
Everything is monitored, and at Swift you take a hit on safety points every time you break a rule.
If you rack up too many points without taking steps to improve your driving, you are terminated.
