I think it's just a matter of who's driving. I have made hundreds of passes in the roadster and I'm OK BS'ing until I start getting the belts cinched down. even then it's usually someone on the crew shooing people away. I don't start trying to get in "a zone" until we light the motor. I have had Al Teague call me over as he was getting strapped, just prior to a 400 mph run, to ask how the course was on my run. I also know people that lock themselves in their push-truck, close their eyes and go thru the run in their heads for 5 or 10 minutes. Here is my suggestion. If someone is sitting around looking relaxed shooting the shit, go ahead and approach them. If someone is tuning everything out around them, eyes focused down the track, avoiding other people, or having a serious one on one with someone on their crew, don't do anything to get in their head. Most people can tell when they are annoying someone. Use common sense. If your talking to me on the line just back away a little when the the starter points at me then points down the track.....the push truck mirrors hurt when they hit you on the side of the head.
