Was watching a NASCAR race on Sunday. There are cameras inside each car, so you can see the driver up close.
I noticed the driver never turns his/her head. They appear to just stare straight ahead.
When I’m in heavy traffic, I am always looking around to see who’s in my blind spot. So how does a NASCAR driver know who’s in their blind spot, who is behind them, who is beside them, etc.? Is there an array of mirrors they look at? Cameras inside the helmet?
