I for one no longer drive more than 5 mph above the limit, even though that's still not technically legal, no matter how impatient the drivers behind me are. I don't hog the left lane, but I'm not going to risk a ticket by speeding up just to save them 5 seconds. If they insist on passing me on the right before I get enough clear space in front of the semi to move back over, then the way I see it, it'll be them and not me pancaked under the semi when things go wrong. I also make sure no one is racing up behind me before I pull out into the passing lane. I will wait the 10 seconds for that car to clear before I move over and start my pass. If another car is farther back than that, but doing 20 mph over, then they still have plenty of time to slow down and wait for me to complete the pass.
All perfectly fine here, because you're being considerate.
Not the case for....
- People in the outer/passing lane but making zero progress on passing, just going side-by-side with the car next to them and preventing other people from passing.
- People going 0.1 mph over the posted limit and making impossibly slow, inch by inch progress on passing. Why bother? Why not just go 64.9 mph behind that car one lane over, rather than 65.1 trying to go around them?
- People who do either of the above and tie up the passing lane for a long time, who then speed up to 80 once they're clear, and then slow back down to 65 again as soon as they reach the next group of cars to prevent anybody from passing them, never moving out of the left lane.
The first two groups are just oblivious for the most part, but the last are the real aholes. People do that on purpose, and I know this because I've patiently waited for some of them to move over for a few minutes after they've passed the last car. They never move though, still going 65.1 in the left lane, and as soon as I go to the right lane to finally "undertake" and pass them, they punch it trying to block me!!!! Apparently it's okay for them to go 80-90 mph to block me from passing, but it's NOT okay for me to just go a casual 70-75 mph to pass them in a 65 zone, when cops don't even bother unless you're 10 over for the most part. These people boggle my mind. This has happened to me more than a handful of times over the years. I think some people "accidentally" do this without realizing they're doing it (fatigued, etc), so it's not all malicious when it happens, but sometimes it is!
