During the Baja 1000 there are cameras everywhere. Tourists have cameras, race watchers have cameras, camera crews for TV and websites have cameras. So you get used to seeing someone being interviewed on camera or even having a camera in your face.
In 2007 we were in the middle of the filming of a movie called Chasing Baja. The major sponsor was BF Goodrich and the movie would air on the Speed Channel before going to DVD. The movie followed one of the Baja Challenge cars throughout the race. My BIL was one of the drivers. As you watch the trailer look for the big bald guy with the cigar, that's my Bro-in-law.
