Looking through the curve

Look where you want to go. That would either be the exit of the curve/turn, or as far up as you can see, if it's a blind curve.

If you stare at the guardrail, curb or divider lines because you are worried about hitting or crossing them, strange and bad things happen:

a) your subconscious mind seems to fight you and go towards what you are looking at but trying to avoid;

b) you scare yourself; and

c) you won't see what's coming up ahead, e.g. debris in the road, curve tightening, oncoming car, etc.
