Just pretend the instructor isn't there and you should be fine. Just try to follow the speed limit, stop completely at intersections, watch out for pedestrians (no matter how retarded they are, they always have the right of way). I wish I could run them over sometimes, but that's another story.
Make sure you don't tailgate (follow too closely to the car in front of you), anticipate turns and traffic. Oh, always use your turn signal.
