While I have no info on this camera speculation, it seems to me any camera install would of the 30 minute loop type. It would be highly doubtful to have real time video, it's too expensive and too much storage for 95,000 vehicles.
It's much more likely a camera that keeps recording the last 30 minutes or so would be utilized and would only be reviewed because of an accident. This makes better sense and would show the company what was happening in the cab moments before an accident.
Was the driver handling the DIAD, on the phone, inattentive, etc?
Time will tell if cameras are on the horizon......but for now, just do the job the way the company wants and these new sensors (when they go live) will be a non issue.
