During the Journey · Principle 5 of Six
Use what you know and what you can see to anticipate what comes next and position appropriately.
Anticipation is working out what the road is about to ask of you. Positioning is being in the right place to do it. The two belong together because neither is much use without the other.
What was planned and learned before the journey, and observed on the approach, comes together here as a decision taken in good time.
Most navigation errors are late errors. The lane is right but taken too late; the exit is the correct one but reached from the wrong side of the carriageway.
A driver who anticipates has time to position, and a driver who is already positioned has no need to make a sudden manoeuvre in order to follow an instruction.
