GTR catches air passing a 911

I doubt it. What you’re hearing is just the driver’s mics being recorded, not just an open air mic on the camera. I doubt they’d fake it and decide to add in feedback from the motor/trans whining.

He waved him, sure, but I don’t care how prepared you are to let a car pass you certainly don’t expect it to pass you at 50+mph more than you over a crest catching air. Especially a land yacht like that behemoth.
