For the tests, Greenberg knew the car he was driving would be hacked, he just didn’t know when or how. The hackers — working from a laptop 10 miles away — promised not to do anything that could endanger him, however. He writes that he was going 70 mph on a highway when the team took control.
At first, they blasted him with cold air and hitched the radio’s volume up as high as it could go, and he couldn’t turn it off. The windshield wipers turned on and sent wiper fluid streaking across the glass. And then, things did get a bit scary: the transmission cut out.
Immediately my accelerator stopped working. As I frantically pressed the pedal and watched the RPMs climb, the Jeep lost half its speed, then slowed to a crawl. This occurred just as I reached a long overpass, with no shoulder to offer an escape. The experiment had ceased to be fun.
After the Jeep gets stuck on an upward slope, with a semi-truck approaching it from behind, he finally called the hackers and begged them to make it stop so he could get out of that tough spot.
