Watch: massive IndyCar crash

If you don't like swearing out loud at an electronic rectangle, do NOT watch this video.

It was taken at yesterday's IndyCar warm-up race in Baltimore and shows Tony Kanaan losing his brakes at 180mph. He launches - literally LAUNCHES - off Helio Castroneves' car, narrowly missing a race marshal.

Incredibly, after he's finished straightenin' the curves, Kanaan, the marshal and Castroneves didn't sustain any injuries. Even more incredibly, Kanaan had his car repaired and went on to finish third in the race.

Now watch. It's mental.
