A US pensioner accidentally reversed his car through the wall of a seven floor building.

Ralph Hudson, 67, got quite a fright when his foot became stuck between his Mercedes' brake and gas pedal as he was backing out of a space in a parking garage in his hometown of Oklahoma. Ralph only managed to stop his vehicle, which burst through the building's exterior wall and sprayed debris on the carpark below, just in time as its back wheels were left hanging precariously out of the building.
