When you get past the noise and the smell, the unbearable heat, the G-force, the surprising physical exertion and, always, the constant threat of injury or death — auto racing, like much else, comes down to math. There is an optimal path around a racetrack, a geometric arc of least resistance. It is the driver’s job to find this sweet spot of physics and stick to it, lap after lap, as consistently as a microprocessor crunching through an algorithm.
For tech people — who are accustomed to finding and manipulating hidden math — hitting the arc can be a moment of particular pleasure.
There's also all the networking going on.
