Yeah, when i was working on mustangs, we had a couple of cases that I had to investigate where a monkey footed mechanic mashed the gas instead of the brake and ran into a wall.
Had another one, where a fleet test driver for a Fusion got off the freeway, and stepped on the clutch thinking it was the brake, never figured out what he was really doing until he rolled out into the desert (after blowing through a red light w/ oncoming traffic) and spun the car out. Even when I was all done and had proven conclusively that he was an arse-hat, the guy insisted that he had stepped on the brake and it just went to the floor. I then asked him if he held the brake to the floor even afterr he finally came to a stop, and he said yes. Then I asked him if he had taken it out of gear, and he said no. Then I asked him if the engine was still running after he stopped, and he said yes. . . He refused to say any more after that.
