There are so many sensations that fans miss out on when they watch a race on television. They don't see just how dramatic elevation changes are, they don't scrunch up their nose at the smell of cooked brakes, they don't feel the waves of air dispersed around them as a pack of cars comes past them at 200 miles per hour.
And those are just the little details you get from sitting trackside. Imagine the feelings that the drivers experience that fans will never begin to know about.
