My Car Won't Start

He tried turning the key several times and nothing happened.
His neighbour appeared.
"Car trouble ?" he asked.
The man nodded.
"No problem, I'll give you a push."
He released the handbrake as his neighbour began to push.
Soon they were at the top of the hill down to the town.
"Good luck," said his neighbour as the car began to roll down the hill.
It picked up speed and he tried to start the car again and again.
Nothing.
Buildings blurred past on both sides. He stamped on the brakes.
Nothing happened.
The river raced towards him.
