I just looked up Smith Training and found a summary at Penhall:
THE 5 KEYS TO SPACE CUSHION DRIVING
Key 1: Aim High In Steering
Key 2: Get The Big Picture
Key 3: Keep Your Eyes Moving
Key 4: Leave Yourself an Out
Key 5: Make sure They See You
That's an excellent list. I was always taught to know everything around you at any second and know exactly where you will head when trouble arises (Key #4).
