Since I'm the OP, I feel safe continuing the threadjack...I mean, I'm "camping" in the left lane because I'm already passing everyone on the right. I also have no qualms about weaving when necessary because someone on the left is "only" doing 75.
No, I'm not going to slow down to 70 in a 65 to move over because you want to go 100.
But MD cops actually enforce speeding, unlike NJ / CT / MA / RI / NH
Here's my business practice for extreme speeders when I'm in the left lane:
1. I'm only in the left lane when passing (to include a reasonable pre-pass distance) or for obstacles, stopped cars, people pulling out, etc.
2. If, once I pass the car in the next lane, there's enough space for me to pull over, you to pass, and me to pull back in without getting caught behind the next slowpoke, I'll move over. Otherwise, you can wait, because I'm likely already doing 10-15 over.
You can find handy rules like this in IKE's Coffee Table Book of Proper Driving. Available ~a year after I retire.
