My wife went down a few days after the Indy 500, and drove an Indy car around the track, and also got a faster ride, with one of the drivers. A gent that was there, driving just before her, had one of these, that they put on his helmet - the suction cup mount. Stayed on the whole way, about 160 mph. I asked him, he said they are great, with HD and almost NO camera flutter, etc. If she decides to go drive again next year, I think I'll get one, then I can play on the Valk (obligatory Valk reference), as well.
Here she is, driving the car:
