I usually drive 80 everyday to school. If I get behind someone going slower, then that's just tough sh!t for me. Just because I'm speeding doesn't make them anymore of an asshole than me. Sure, it's not very courteous, and might not exactly be legal, but oh well. Who hear can honestly say that they have NEVER pissed someone off while driving. Get over it, because no amount of honking, flashing, flipping the bird or shouting will make the minute or two I lose (If that) from going slower worth it. Yeah, it's annoying. Big deal. You might lose a minute. Get over it. Even if time is money for you, that's what, 20, 30 cents? Is getting pissed off with only your steering wheel to hear you worth that much? Get over it. Getting angry is just going to make me do something stupid, and stupidity has NO place behind the wheel of a car. 50% of driving is prevnting mistakes. Nothing that ever happens on a freeway justifys being a rude driver, even if it is in response to someone else's bad driving. The other 50% of driving is compensating for other people's mistakes, and if that means slowing down and being patient, then so be it. I'd rather get to school late than get to school later with a smashed front end. It would be my own damn fault for not leaving earlier and thinking that I would have a perfect drive to school.
From the standpoint of the person going slower: There's nothing I hate more than having someone blind me with their brights or riding my ass and get angry just because I take a few precious SECONDS from their day by trying to pass someone. Driving in the left lane may not be legal, but as someone said, two wrongs don't make a right. As long as (as a bare minium.) I'm going the speed limit, then you don't deserve to get angry at me. It would be a different situation if there wasn't a single car on the highway, and you had to go around me, because changing lanes at a higher speed is MUCH MUCH more dangerous than speeding itself. But when the freeway has moderate traffic, even going 65 is usually actively passing people and it would be more dangerous to keep lane jumping. I will be more than happy to get over if you can wait until I can safely do so, but if you think that riding my ass and honking as a constant reminder is going to make me do it any faster, you are sorely mistaken. Your ignorance while driving makes making a safe lane change even HARDER, because you are distracting me from checking my blind spots and paying attention to the road. Sorry to all you speed freaks out there who think that your car is a bulldozer, but you can kiss my ass if you think that you endangering me is somehow justification for saving yourself a few seconds on your drive to wherever you think is more important that my life, and the time of the other people on that highway.
Basically, no matter of the legal standpoint, being unsafe is far worse than breaking the law or being uncourteous. Count your blessings and leave the anger off the road.
