So, Maryland allows drivers to drive in the left lane at the speed limit and does not require them to yield to faster traffic.
I wonder if this is because of the amount of left exits. There are a significant amount of them which requires all vehicles exiting to move to the left lane (fast lane) to exit.
Everybody hates them because they slow traffic down, but the roads are so dense and criss-crossed that sometimes they are the only solution.
I generally speed, like most drivers in Maryland. When I am in the fast lane going faster than the other 3 lanes of traffic (and probably directly behind another vehicle), do not come up behind me flashing your highbeams and tailgating me to make me move. First off, I am speeding as fast as traffic allows and there's nowhere for me to go, and secondly, your riding my ass with your highbeams on in an attempt to annoy me is only going to piss me off.
The last time this happened, I tolerated the deliberate and continuous use of highbeams at night for a few miles and then I slammed on my brakes. The lady behind me had to run off the road to avoid hitting me. Had she rearended me, it would've been her fault per traffic laws. She got back on the road and caught up to me, but she coudn't get around me because there was so much traffic there was literally no way. She engaged in angry, erratic lane changes behind me, but could never get ahead for the next 30 miles. I finally had to exit and she blew around me, flipping me the bird, but she had gotten absolutely nowhere in all of that time.
My vehicles are old, so go ahead and rear-end me. Her car was new, however, so hitting me would've been bad for her. The same principle applies when you have to merge onto an interstate that is crawling. The only way to do it is to cut someone off. You always pull out in front of a nice, expensive vehicle. They are going to do anything to avoid a collision.
These are the kinds of problems that happen when roads are so crowded that normal road rules can't be followed. Yes, I'm going to have to cut you off in order to merge on on the highway. The only worse thing is when someone comes to a dead stop when they're having trouble merging into traffic. That really screws traffic up and causes rear-end collisions.
