I did lose a whole car once. 1960 just out of high school I'm driving a beat out old International tow truck for a wrecking yard. No hydraulics, just a hand cranked winch with a dog that dropped into the main gear. Flying down the highway, the dog jumped out and the old Pontiac with no front drums hit the pavement. The backing plates left 2 beautiful grooves for a couple hundred feet before I could get off the road. Fortunately I got it lifted back up and fled the scene before anyone showed up.
