Actually, that comes from a couple of things. That many cars all trying to fit into one space, well, you're going to have some bumping and banging. There's no way to avoid it. Sometimes you feel like the whole race is one big wreck with a race in the middle of it. Another thing that leads to a lot of bumping and banging is the brakes and how you use them at Martinsville.
Brakes are just about everything at the place.
And they'll talk about them all day long. Every other driver is going to be hearing the same thing. So you're spending the day thinking about the brakes and any way you can to conserve them. There are a few guys out there who conserve their brakes by using the cars beside them or in front of them. What they do is go into the corner a little harder than they normally would and bank off the guy beside them, or just kind of gently stick it into the guy in front of them.
