Remember that you’re not being assessed on how well you predict what is going to happen, you’re being assessed on how you deal with is happening.
Approaching green lights at a junction that have been green for a while? You don’t ease off because you predict they might change, you ease off because they have been green for a long time and it’s likely that they will change before you get there.
Waiting at a roundabout, you don’t have to predict what the ■■■■ in the Audi coming around the inside lane with no indication is going to do, you don’t go because you don’t know.
