I think fear is what keeps us from going over the edge. I mean, as a race car driver, I don't think what makes a good race car driver is a fearless person. I think it's somebody that is comfortable being behind the wheel of something that's somewhat out of control.

When you're in a race car, you're going through so many different emotions throughout that race.

I thought long and hard about my future this past year and during the offseason, and I've decided 2015 will be the last time I compete for a championship.

In California, especially Northern California, the fans really cheer for me.

If somebody tells me, 'You have to pass that car right there,' I guarantee you I'm going to step up the aggressiveness to a whole other level and that may mean beating and banging. But until it calls for that moment, I'm not expecting to go out there and just beat and bang for no reason.

Our fans would never waste good beer by pouring it on us.

No matter what happens, I'll always say that I've had a wonderful life.
