I was always too short to properly see out the windows of the car, and wasn't allowed to sit in the front, so I never saw out that way either. Now, have you ever seen a movie that shows a person driving down a perfectly straight stretch of road while turning the steering wheel madly back and forth? These two things in combination led me to believe, for a while, that whatever let the wheels of the car turn wasn't really connected to anything. They just sort of floated around by themselves, and you had to turn the wheel in order to keep them pointing in a straight line so the car would stay on the road.
