Not entirely, IIRC in 2006 Robby Gordon was fined $15,000 and docked 50 Drivers and Owners points for throwing a bit of roll cage padding out the window and creating a full course yellow at Atlanta.
On Sunday when the F1 drivers were pulling away from their pits, I noted that they were ditching visor pull offs. It seemed a funny time to do it, but of course, there is no other time. The drive into the pit is too busy for the top drivers and they can't just lose it on the straight as in years past.
