My father in law has been a trucker in the US for a long time, and really enjoys it, or rather used too. Video cameras being installed in the truck cab are the reason he's changed his opinion. In every way he is an upstanding citizen, employee, and driver, and even though he's passed retirement age he enjoys driving seasonally. I think this will be his last season due to the cameras.

I know that if someone was watching me during all working hours I would also look for the exit.
