Motor racing is one of the few sports where you are taking your life into your own hands every time you compete. One mistake, either from yourself or your vehicle, can cost you your life and that very nearly happened to Japanese driver Shigeru Terajima here. He was ok but after seeing the nature of the crash he can count himself lucky.

There is always something terrifying about seeing a big auto racing crash.
