Roadrage is an almost non-existent phenomenon in Japan. Japanese drivers draw upon un-natural reserves of patience as they inch through traffic jams kilometers long. I [an Australian in Japan] am unable to do this - I'm either zooming down the middle on my scooter, or banging my head on the steering wheel in frustration.Many people here believe roadrage is natural and understandable. It's part of the human condition. It's logical. It's well and good. It can't be got rid of.
But that's all false. It's just memes giving people entrenched hangups. It's pointless, bad, and as any Japanese person can tell you, it does not have to be that way.
