The drag thing, turbulence thing....not difficult for pilots to understand
But even some of my mates who were astronoooghts don't quite get the leg thing, saw a guy at our local track on Wednesday doing it.....as I past on the inside, and I'm the one who gets overtaken by a joe family with a caravan while commuting on roads
yea anyone i have met at a track day doing the leg drag is usually painfully slow, but it always makes me laugh.
