I had a similar thing happen but no cops and not as long of a time.
Pulled up to a red light behind a flatbed tractor trailer, waiting for the light to change... clutch pressed in, still in first gear.
Suddenly I wake up to a slight bump.... I had drifted off and the truck had slowly drifted forward into the back of the flatbed. I was asleep with my foot still pressing the fucking clutch The truck driver never noticed and drove off when green happened, and I had no damage to my truck ... like it mattered, it was a $900 1992 Explorer.
