The guy in shorts in an Englishman, visiting his girlfriend here.

It turned out that he is not used to the location of the brake and
the gas pedal in European cars. He started the engine, released
the clutch when in first gear, then slammed on the brake when
the car lurched forward.

Well, that brake was in fact the gas pedal, and thus they went over the edge.

At least, this is what his girlfriend says.... :)
