Charlie Miller lay across the front seats of his Fiat Chrysler Jeep while it drove, seemingly by itself. Suddenly, it jerked to a halt, as his research partner Chris Valasek, sitting on the other side of the car park, used a laptop to slam on the brakes.
Mr Miller and Mr Valasek, car hackers, prompted a recall of 1.4m Fiat Chrysler vehicles last year after a magazine detailed how they accessed a radio to disable a Jeep’s transmission as it drove along a road. Now they are back at work, showing that with initial physical access, they can trick a car into speeding up, braking, or force it to ignore a request from the emergency parking brake.
But they do not think car-makers are taking them seriously. “They all say their car couldn’t be affected,” the pair said.
