Driving is a sort of exchange. It's not done in isolation: there's action and reaction, both by you and of you.
And like any trading, of goods or information, a driver needs to understand their current environment, how that affects what they do next. Move (= sell/buy), or wait? See who else moves first?
Pause and take stock. There's seldom a real rush. You want repeat business (= multiple successful journeys), not a single transaction. You want others to have confidence in what you're doing. They'll then share the marketplace (= road space) with you.
People who can't tell what you're about to do won't want to come anywhere near you—you'll be "too risky a business".
