Over 70 years ago I remember watching as a child left in the car pressed the starter, the old car jumped the curb and drove through a shop window, it made a big impression on me.
It was probably in the days when cars had a foot pedal to operate the starter, that's going back a while.
A motorcycle left in gear would launch itself off the side stand if cranked, kids love to push buttons, of course we would never disable the stand switch, but my old Eldorado never had one of those.
