It was the best of times, it was the worst of times. One thing I hardly ever ever ever do is make eye contact with someone else in another vehicle. I don't like to do it. Now this is in complete contrast of the people watching I do.
I will look at other people, out of boredom and curiosity...but if I sense they are looking at me, or going to look at me...I look away. I don't know if it is a good thing that I do it. I'm not shy, I'm not afraid, and I'm not escared. Am I anti-social? I dunno. I know some friends who smiled at each other on the freeway...now they are married. Kinda cool...nice..romantic. Then again, who knows you could be looking at some psycho or axe murderer!
I suppose smiling wouldn't hurt or even give a confused look. Sometimes I hide the smile when they have their arm up into their nose picking, all the way to their elbow. Now that's pretty funny. I should just laugh at them to make them stop. Heck next time I see a nose picker I'm going to lay on the horn. Maybe then they'll pluck their brains out or at least stop.
I always notice truck drivers looking down at the cars going by more so than anyone. Even motorcycle people. Do you want to see or be seen? What's the deal? Do you have to look at every car that goes by? Do you really think that hot chick is going to stop and pull over and ask you for directions? Yeah Mr. Motorcycle dude, we know you are cool. Yeah Mr. Truck Driver we know you are over compensating.
Don't look at me when I'm driving...because I can't look at you when you do. Got it?
