From my seat at the race I saw the entire accident unfold. As soon as I saw him (his name is spelled Dixon btw) get out of the car I remarked at least the race will receive some national attention - it's a shame it takes a spectacular wreck to bring the attention to a great event.
Having F1 champion Fernando Alonso here brought a lot of international attention and Takuma Sato winning will be huge in Japan.
Sato made this last lap pass attempt to win the 500 in 2012:
