If it is the one I am thinking of, it was a regular with one of my senior courses - who had an old fiat 500 - to set the car in motion at one end of the bridge, jump out and swim the river and make it to the other side before the car got there.
This was early 80s and the Fiat 500 had a choke/ fast idle lever next to the handbrake which gave about 3 mph in first gear - who said driverless cars were new?
