I had to learn that same lesson on the race track. I’d get passed by much faster cars and try to keep up with them to learn they’re lines and anything I could. Sure as shit, I’d follow right behind into a corner and go right around.
Race days are always complete chaos! To much happens even to mentally digest it all. Driving home from the races, physically and mentally exhausted, my Wife and I rewind the events of the day. What happened with so-and-so in the first heat race, why did you make that change and make it worse, it was great how Joe & Jim helped you bleed the brakes, I had to help Tim with front end after I put him off, etc
Good luck with that vibration!
