Following the script of the movie Speed, the vehicle would not decelerate below 30mph (50kmph). Morrison managed to take steering control and dialled 999 for help.

The police "carried out a controlled halt" on the unmanned vehicle, stopping it from driving away with the van's brakes until a roadside assistance technician arrived three hours later and managed to shut it down.

"When the [technician] got to me  later, he plugged in the car to do a diagnostic check and there was pages of faults," said the "kidnapped" driver from Glasgow. "

He said he had never seen anything like it and decided he was not willing to turn the engine on to see what was wrong.

He said he was lucky that the incident had taken place after 10 pm on a Sunday night when the roads were quiet.

"I realised something was wrong when I was coming up to a roundabout and went to slow down but it didn't do it," he said.

"Then I heard a loud grinding noise that sounded like brake pads, but because it was such a new car I knew it couldn't be a problem with them.

"I managed to get around the roundabout going at about 30mph and then had a long road ahead of me, so I assumed it would stop without me accelerating - but it didn't."

Police asked Morrison to throw his electronic key through their van window before driving off, and then tried forcibly shutting off the engine - but nothing could stop the car.

He was also asked to hold the power button for a couple of seconds which also failed to stop it and the entire dashboard lit up with faults.

Morrison said: "Eventually I came up to a roundabout which slowed the car down to about 15mph and the police van was waiting for me on the other side.

"I went into the back of the van while it was moving, before they put on the brakes to stop me.

''After that, a police officer jumped into my car and did something which seemed to keep the car still."

A Police Scotland spokesperson said: "The car was travelling at a low speed and officers carried out a controlled halt with the aid of a police vehicle. There was no damage to either vehicle.
