Its a garbage system. If you move the truck it just logs your drivers on, so if I go at night and hook a truck up to a different trailer or something, the machine will log onto the last driver of the truck. Now when he gets in in the morning for the shift, the computer is telling him he only has 6 driving hours left. You spend more time changing and editing e logs for issues than you ever did paper. Administration costs are higher. The perfect system would be paper logs, backed up by a gps chip. So they could still investigate the trip if an issue came up.
