The incident occurred on a Sunday night when Morrison's MG ZS EV got stuck at 30 miles per hour (48 km/h) on the A803 in Scotland.
Morrison noticed a problem when he tried to slow down as he approached a roundabout but found that the car did not respond. He heard a concerning grinding noise that resembled brake pad issues, but given the newness of the car, he suspected it was a different problem.
He managed to navigate the roundabout at approximately 30 mph and continued on a long road, hoping the car would come to a stop without him having to accelerate. However, the car did not stop as expected.
Alarmed, Morrison contacted the police for assistance. Three police vehicles arrived to escort him and the out-of-control car. They attempted various methods to turn off the engine, including having Morrison throw his electronic key out of the car and pressing the power button for a few seconds, but the car remained in motion, displaying faults on the dashboard.
The police eventually intervened by positioning one of their vans in front of the MG ZS EV and gradually slowing down to execute a "controlled halt." Morrison had to intentionally rear-end the van at a low speed to stop the car.
This frightening experience left Morrison with concerns about driving electric vehicles, particularly due to the loss of control he experienced during the incident with his MG ZS EV.
Fortunately, at that juncture, the car had decelerated to approximately 15 mph (24 km/h) while on an incline, resulting in no injuries and no damage to either vehicle.
The police had to maintain the position of their van in front of Morrison's car because whenever they attempted to move the van, the MG ZS EV would start moving again.
Upon the arrival of roadside assistance from the Roadside Automotive Club (RAC), a mechanic conducted a diagnostic check on the car and identified numerous faults, prompting concern. The mechanic stated that he had never encountered such a situation before and opted not to start the engine to assess the issue, considering the potential risks. Morrison shared these details with the BBC.
