I believe I saw this before but I didn't remember most of it -- aside from the great pachinko scene. In the English translation I heard, Jackie trained with Mitsubishi, went back to China to be a mechanic, then had to race in Japan. We don't know if he ever got to race or did anything in Japan other than hurt his hand, but somehow the pit crew boss has enough latitude to give him a spot for a high-profile race.

His relationship with the cop is also odd (read: stupid, three times over).
