Brian Morrison ended up a prisoner in his own new MG electric car that wouldn't stop. He could steer, but the brakes didn't work, and he couldn't turn it off.  At one point he threw the car keys into the police van driving beside him, which had come to help, but even that didn't stop the motor. This was not meant to be a self-driving car.

Tragedy was averted this time because it was 10:30 at night, the road was empty and the police had time to stop it. But what if this fault occurred in normal traffic and the EV drove through a red light, or a pedestrian?

I was kidnapped by my runaway electric car

Terrified motorist, 53, reveals his new £30,000 MG ZS EV 'began driving itself' after suffering 'catastrophic malfunction' – forcing him to dial 999 and crash it into a police van to get it to stop

Brian Morrison, 53, claims he was heading home from work at around 10pm on Sunday when his new Chinese-made fully electric car began driving itself at 30mph.

'I have mobility issues, so I couldn't even jump out – I was completely trapped inside the car going at 30mph.

'So eventually three police vehicles arrived and were driving in front of me and behind me.

Mr Morrison said: 'After trying to shut the car down, my entire dashboard lit up with faults, and then it all went away after a second and just had a big red car symbol that said "drive safely, stop driving immediately" or something.
