The left lane is the fast lane, so why do people insist on going 10 mph slower than everyone else? Let the cops pull them over if their speeding or being slow excessively. Its just drivers etiquette. If a guy is speeding, and trying to cut you, then I quickly either try to get out of the way. Because, a) if he's reckless, then I seriously don't want to be the one getting hit by him. b) I have stuff to do, the last thing on my checklist for the day is to get in an accident. c) I live in NOVA. Northern Virginia is known for having one of the worst driving next to NY/DC.... d) People who are rude by their drivers etiquette, are people you normally wouldn't want to deal with on a regular normal basis, so I just get out of their way. And move on with my life.
No need to frustrate or p--- them off. People who do things like that have a reckless abandon, and don't mind doing the craziest thing. I've seen a car cut a huge 16 wheeler with almost 3 inches of space, and had an accident occurred. 5 cars behind them would've been screwed.
People nowadays literally have no manner. They don't care that their reckless driving either by speeding, making dangerous cuts or turns, or tailgating.
I think tailgating is absolutely rude, because it makes people unsure of if you'll hit them. I used to brake a lot to tick them off, but no longer do it. Just a waste of my time, and do I really feel happy about myself doing exactly and essentially the same thing their doing?
