45mph construction zone on 465 NE leg
For context, I've already received a ticket for going 56mph in this 45mph construction zone on the NE leg of 465. So when I drive through there now (4 times a week), I set my cruise to 55mph and stay in the middle lane (they'll give you up to 10mph and not ticket you).
People are totally insane though, flying through this area at 70, 80mph and antagonizing people who don't do that. Yesterday I was in the middle lane and I had a semi fly around me in the right lane laying on his horn and flipping me off. Then, I'm still in the middle lane doing 55mph. Some guy camps out behind me two inches from my bumper for a couple miles, so I slowed down to 50mph (didn't even hit my brakes, just eased the cruise down to 50). He goes around me, then gets in front of me and brake checks me! This particular day was an extreme example, but these are not the only incidents I've experienced the last few months on this stretch of road.
What is going on? Is someone who is trying to abide by the law (or at the very least, attempt to respect the spirit of it) that out of the ordinary? I'm truly at a loss as to what to do on this stretch of road in order to not subject myself to this kind of abuse.
