Usain Bolt is no stranger to speed but the world's fastest runner admitted he thought he "was about to die" as Lewis Hamilton drove him around the Circuit of the Americas.
The pre-race stunt, in a lime-green Mercedes AMG roadcar with No 1 emblazoned on the livery, put the wind up Bolt, with Hamilton saying: "I was on the limit. We nearly crashed several times. I wasn't looking where I was going. Don't do that at home.
"He may be the fastest dude in the world, but I thought I would scare him. He had to retire before risking doing that with me, but it's an honour to have him here."
In a video of the incident, posted to Bolt's official Instagram, the eight-time Olympic champion screamed: "I wasn't ready. You tried to kill me. I made it, but you tried to kill me."
Hamilton completed a couple of laps with Bolt on a day the sport's new owners, Liberty Media, tried to put the Super Bowl into Formula One.
