Much in the same way with my Corvette (74 W/built 350) When a young guy pulled up to the stop line, gunning his engine wanting to impress his girlfriend in the car, when the light changed I just rolled off the line "Normally" he laid into it.
After, my son looked over at me wanting to know why I didn't "Blow Him Away". I looked over at him and said "Sometimes in life it's enough to know you could have if you wanted to, not that you did". About that time a Police car went past us with the lights on, pulling over the other car, he looked over at me with a little smile, "I think I get it dad".
I miss the "Zip" of my GSXR not that I needed to use it all the time, just knowing it was there.
