Sometimes I despair!
A couple of weeks ago there was a TV news report on someone who backed their car out of the second level of a multi storey car park, & was left dangling perilously "half in, half out".
The newsreader stated that the driver "Put her foot on the "reverse pedal" by mistake." 
I think Ford "T" models had something like that, but I've never heard of it otherwise.
I wouldn't be surprised to find a Citroen with an arrangement like that, they've had all sorts of odd arrangements over the years. A former boss had a high end Citroen that I inherited after he left the company and I had to drive for a (mercifully short) while. It had the handbrake release on a pedal to the left of the clutch pedal, which made for very
interesting hill starts involving a little right foot dance between brake and accelerator while doing a left foot dance of release handbrake, declutch, engage 1st gear, find clutch biting point without stalling.
