NASA FL does passing a little different than what I'm used to. Up north most clubs get to a point where it's pass anywhere with a point. NASA's HPDE3 was pass in the straights, either side, no point by required. That was weird on the turns that went from left to right or vice versa. It took me a while to get used to it because I would point guys by anywhere...especially because I was puttering down the straights trying to cool the car.
IMHO, passing anywhere with a point is far safer than straights without a point. Communication is the key to safety on track and when you don't keep people communicating (in a non-competitive event) accidents happen.
For the record, there were many point-by's by many people. I always did unless it was in the middle of a straight going 70mph.
