Thats it!!! Piss tests for drivers!
I find that I get the shakes at times as well. Especially since I moved to 1/12th scale last season. I especially got nervous once when my Fiance' came in unexpectedly while I was in the last qual. For some reason, having her watch me drive the car around the track made it the worst because I guess I subconciously wanted to impress her.
In that qual it was like 3 mins down and I saw her and plowed right into a corner. I stopped, looked at her and she just smiled and said "go..."
I relaxed and tore up a TQ lap. She then went and picked up my car and handed it to me saying "do I really scare you that much?!?!?"
It was funny...and I'll never forget it.
