It's easy to dismiss racing as a sort of silliness that has nothing to do with the exalted heights to which we nerds aspire. As the two Irreal posts show this is far from the truth. Racing, as it's practiced today, is extraordinary technical with enough serious challenges to occupy any of us.
I'm still not a racing fan but I do admire the technical challenges that they've overcome. If you haven't seen my first post, take a look at it and follow the links: what the pit crews do is nothing short of extraordinary.
