our driver pointed to the car parked next to us and there was a little boy, about 3 or 4 years old, sitting in the drivers seat. He had started up the car.

I opened the door and turned the engine off and asked him where his mother was. He got out of the car, grabbed the keys from me (quite rightly I suppose lol) and headed across the road to the house opposite. I followed, and his mother was just coming out of the house. I explained he'd started the motor. She just smiled.

Jeez! He only had to hit the gear stick and whooooooooosh! the car would have bolted forward into the tree in front of it.

Not clever, Mum!
