I have so many stories like yours from when I was doing the Grand Prix stuff. I can't count the times I was laughed at in the staging lanes by muscle drivers only to dust them by, in many cases, whole seconds.
One I remember in particular was an LS1 Corvette in the lane next to mine, three cars back, at Norwalk. Driver walked up to me with several of his buddies in tow, asked if I borrowed the car from my Mom, laughed in my face, and said I should get a hold of something fast like his Corvette. "You'in need a real fast car like my Vette!" was about what he said.
When I got to the strip, I had the official hold me so I could get lined up with him. He just laughed and shook his head. I beat him with a 11.7x to his 12.3x and three miles an hour. We were both on DR's.
He didn't look at me at the end of the track, and I gave him plenty of opportunity. I saw him and his buddies in the staging lanes two more times and none of them would look me in the eye.
