To be a race car driver back in the day you had to be a little crazy in the head. At least now there's cutting edge technology to help protect that head.
On a recent episode of CNBC's "Jay Leno's Garage," 26-year-old NASCAR superstar Joey Logano meets up with Jay Leno at the Auto Club Speedway in Fontana, California, to go around the track in a car that's more than twice his age.
Logano is already a legend. He holds the record for being the youngest winner in two of NASCAR's top three divisions. And in 2015, when he was just 24, he became one of the youngest drivers ever to win the Daytona 500.
He's so good, in fact, that his nickname is "Sliced Bread" because, in auto racing, he's arguably the greatest thing since that.
