A German mum almost lost her car and her children when her five-year-old son started the ignition and nearly drove over the edge of a harbour.
Sarah Kaiser, 28, had just finished shopping at a Dusseldorf supermarket and returned to her silver Peugeot car which was parked next to the Rhine.
She told local police: "I put the key in the ignition to use the electronic button to open the boot and load up the shopping - and I left it there as the engine was not running."
But as she was strapping in her two-year-old daughter, her son David sat in the driver's seat and started turning the steering wheel - and then turned the ignition key.
The starter motor then sent the car jumping across the car park with the front wheels toppling over the edge of the harbour.
She said: "If it gone over the edge it could have been a disaster - instead my son had a very valuable lesson and the car was not damaged.
"But either way I will be more careful with the ignition keys in future."
Local police and firemen helped put the car back in a safe place, and the woman was allowed to drive home with her repentant son.
