The road is not a race track..... stop treating it like one. I swear that those 'people' do as much to harm motorcycling as loud-pipes and squids combined.
He was doing fine until he lost concentration, caught some paint, maybe a little target fixation or trying to let the bike behind him pass, but the road is a track. Just remember your track is one lane.
He wasn't doing 100 MPH, look at the speedo, he was going from 50 to 70, the 106 you saw was the time.
Object fixation. He was looking at the oncoming vehicles and that's why he got himself into the near-fatal-statistic category. If you're going to go fast, pay some FREAKIN' attention!
