Sure you do. You look down a street, both ways. If a car is waaaay
down the street, and moving at a certain speed, you may or may not
cross the street, depending on the distance and speed of said car.
You may not take pencil to paper, but your final decision is based on
basic mathmatical factors such as distance and speed. I bet you
didn't know you were so smart!
