Too much thinking going on... You are supposed to think about what your going to have for dinner and drink for the evening while you are riding...
Things like..
"I think I smell a BBQ..." (next time around) "Yup, I did!"
"Did I just kill that poor butterfly"
"That a**hole thinks he is going up the inside... well I got news for him!"
"Bet I can go into that turn harder and faster this time then last time"
And yes... I am being dead serious about overthiking all this. Humans can't process that much information in those time frames... It has to become learned reactions IMO...
In 4 years of racing, I don't think I EVER picked a brake marker other then... "Turn coming... turn coming.. turn coming... NOW".
Maybe others can... but I couldn't do things like pick points and expect to react... Maybe that is why I was always "lucky" with respect to highsides... by the time I figured out what was going on, the bike had straightened out and I was long past the point of interfering with the machines abilities lol...
