Thanks for sharing that. Nice in car setup you have there. I still prefer looking at 911's like yours on the track.
Thanks I use Harry's lap timer for iPhone. Have a Bluetooth obd which it talks too (get boost, Rev, gear etc). and also controls my go pro which I mounted on the helmet for first time (normally mount externally). Harrys Laptimer puts it altogether for you, and produces what you watched.
I know some groups put an X on the back of a car with a driver who is new to the track to alert other drivers to that fact. This is clearly not US though so maybe not that.
