We see it more and more often, athletes who perform crazy stunts to impress us. Recently we had an athlete who trained for a long time to jump over a Lamborghini Gallardo which was driving 80 kph! Now we've got an athlete who wants to jump over an Audi R8 V10 which is driving 140 kph! How crazy do you need to be to do this? Even a better question, how do you train this?
