What we've learned on the track

[Quickurt]

Excellent comments and additions!
I like the "running scenarios" description. Great way to describe the technique.
On the track you know in a short time where you can and can't go to avoid something, because you go around and round, lap after lap, and you've probably had an old hand at the track tell you about that particular track's "bad spots."
On the street, it's another story, unless it's your daily commute route.
So, I constantly watch for "can't go" areas: deep ditch swales next to the road, driveway culverts, walls, deep center medians, etc. In that way, if something does happen you must avoid, you are aware of directions that are off limits, which greatly shortens decision times for taking action. You will also learn to be aware of these danger spots in watching your "vision scene" and you will begin to find yourself glancing at them, to log all of the details of the hazard, and then returning to your "down the road" view.
Also, the street has other hazards the track does not. ANY TIME you break left, in an attempt to avoid a serious situation, you are putting yourself on a path to a possible head-on collision. You may be on a divided highway, but if there is no center wall or guardrail to stop your momentum, you have directed your car toward a head-on situation and you will then have to change directions again to avoid going into the oncoming lane.
Another rule to remember: ANY other type of collision is always better than a head-on collision.
