Nascar fans, when they show the in-car camera (roughly from the front passenger seat, if it was a passenger car) - what is the bar, along the driver's right temple, with a logo on it? My dad told me it is to protect the driver's head, but it looked to us like it was far enough away from the driver that his (helmeted) head could easily bounce against the bar. Is it to protect the driver? Is it closer to him than it looked on TV?

Thanks,
Elyse
