Never outride your sight distance; be able to stop on the road you can see, even if you've been on the same road a thousand times.
Never accelerate into a situation that looks out of the ordinary for any reason. As a matter of fact, when approaching a situation that looks strange (car parked on the shoulder, people near the road, etc) it's a damn good idea to drop 10 MPH from your speed if it is safe to do so.
Trust your gut.
Learn how to brake hard and practice it at least once a season, preferably more.

Badasses might screw with another badass. Nobody screws with a nut job.
