Mario Andretti

One of only 3 drivers to win in 4 different decades.. the other two were Foyt and Petty.

One of only two drivers to win in Formula One, Indy Car, the World Sportscar Championship, and Nascar

Was once pulled over for speeding in Santa Monica, and the cop asked "Who do you think you are? Mario Andretti?" No kidding, it really happened. He was interviewed by Hot Rod in the Jan 2012 issue, page 16
