Something similar was installed in every front line vehicle driven at Waste Management not in supervisory or management vehicles. Originally intended for use in 'coaching' of driving habits, the camera's quickly became a disciplinary and in cab observation tool. Drinking coffee or a soda, eating a candy bar or snack became a reason for a three day unpaid vacation. The above is the reason the site I used to work at has a high turnover rate, and 40% of the drivers are new hires. That's really good for safety.
If said camera's are forward looking only, maybe. I'll not be monitored for the amusement of management or some functionary at an insurance company.
