Auto Race (オートレース, Ōto Rēsu) has its own history.
It takes heart, dedication, and probably other things, but I don’t speak Japanese. I just dig that outfit.
But there are challenges to running these small circuit races. There are no bales of hay, long sandy shoals or other zones designed to absorb the momentum of a careening motorcycle and driver. The life of a rider is hard, and often away from home for half a year. and it takes heart to make it.

The video above is another “public game” in Japan. You can gamble on it. This is a 360 video. There’s contact at 3:59 off starboard. The POV is from a racer who takes a really wide left turn, so turn the camera view to port, (to the left), to see the other riders using these boats like cheap ponies. Also, I’m a cat. They train hard!
