Sailboats. On board our boat we have an "apparent wind" speed/direction indicator. But truth tell, it's a constant mental evaluation of vector analysis: Wind from here, boat going in this direction, speed so & so, waves and current pushing the boat this-a-way.... constant vector s (IN THE HEAD ! ) .
More real life you want? Bad guy runs out of the (place) and cop decides to shoot --- wind speed, movement of target, movement of shooter.... mental vector analysis.
Ask again if this doesn't answer your question....
