Kyoto

I went to Gion on Monday, last Monday. I'm not sure if you guys know but there was an accident in Gion last... Saturday? Maybe? A man passed out while driving and drove right into a crowd of people. Seven or eight people died and ten were badly injured. When I was in Kyoto I was with some friends and they felt real uneasy around that area. Japan is kind of superstitious about the supernatural. They believe that that spot where the accident happened will be an area for future accidents because of the negative energy left from those who died. I wonder what caused the man to pass out at the wheel.
