My wife and I drove about 16 hours over the last three days while visiting our daughter in New York's Finger Lakes region. We took major highways on the way out and split it up on the way back, using the NY Thruway and backroads in Vermont and New Hampshire.
On the major highways, people drive in the left lane regardless of speed or whether the right lane is free and clear. If they are in the right lane and are approaching slower cars, they don’t wait until it’s safe to move over. They just signal and move over. Whether no one is behind you is irrelevant. It’s better to squeeze in between you and the car in front because the signal makes it their right to force you to slam on the brakes and let them in.
When you are behind one of the permanent left-laners, the ones behind you will inevitably ride your ass. The car in front of you is irrelevant - you should be using your special powers to pass them.
And above all else, you must accept that you are the asshole.
Once we were on the backroads, most waited their turns, and it was much less stressful. We did see one person pass five cars and then push it for a sixth in a no-pass zone around a blind corner. But he was far enough ahead of us that we would have witnessed his crash rather than been part of it if someone had been coming the other way. As it turns out, he just missed an oncoming car by a few seconds.
But if you are a pedestrian or on a bike, it’s not the same.
