There's a total lack of "lane discipline" (as Clarkson would say) in the US. In fact I'd argue that it's not a lack of discipline, but just a lack of understanding of how you should drive on a highway.

People tend to migrate to the "fast" lanes (the left), so you naturally end up with people either passing on the right or tailgating them. Of course, you should always be in the right lanes except for passing.

I do wonder if let's say there's someone in lane 3 of 4 going slower than the limit and you can pass them safely on the right in lane 1 that it's probably safer to just do that (assuming you're not flying along!) than moving over 3 lanes to the left, passing then moving 3 over back to the right.

First, I should note that I 100% agree.

However, as the highways have become more crowded, it has become less practical to actually adhere to this.

If I'm going 70MPH (the prevailing speed on the NYS highways where the legal speed limit is 65MPH tends to be somewhere between 70 and 78MPH), and there are a half-dozen cars going 60MPH in the right lane, with just barely enough room between them to safely get in (ie, there's sufficient stopping room between the rear car and me, and between me and the front car), then technically I could pass the first car, pull back into the right lane, pull almost immediately back into the left lane to pass the next car, and repeat several more times. But that's not merely tedious, it's dangerous.

It's even worse when instead of a half-dozen regular cars going 60MPH, it's three tractor-trailers. Particularly since "safe distance" for them is much longer due to visibility issues.

...And, of course, sometimes when I'm doing this, some yahoo going 80MPH will zip up behind me, pass me on the right (completely ignoring the aforementioned safe distances) and then zip back into the left lane to careen onwards.

The way I like to think about is this: If I see a maniac looming in my rearview mirror, where do I want that driver to be? Surely not bottled up behind me, where they can cause all kinds of trouble. I want them out in front of me, where I can keep an eye on them and where I control the distance between us. Furthermore, I would like to put this nutjob in front of me as quickly and as cleanly as possible. Fortunately they are often happy to zip by on my left if I give them the slightest encouragement: Room to do so.

Exactly. Cars who want to go faster than me: I want them ahead of me.

For the same reason, I want cars who wish to go more slowly than I do to be behind me.

I used to adhere to this but it does not work in practice.

Right lanes have the highest churn-- people getting off, people getting on. If you're not planning to do either, you have no business being on that side of the road.

This idea about left lanes only being for passing only ever works when you're overtaking a tractor doing 15mph on a country road. The concept does not scale to freeway speeds or traffic. You're not legally passing anyone already doing 70.

I couldn't disagree more strongly :). I always adhere by "keep right except to pass" and it works fine. I also move into the left lane preemptively while approaching an on ramp to give any traffic entering the highway room to merge. I'll be honest, I usually set my cruise control about 10% over the speed limit, because I find I can minimize the number of times I have to change speed this way. Decelerating only to accelerate again wastes fuel so I do whatever I can to maintain a constant speed, but I also want to get there ASAP. So 10% over seems to be the sweet spot--sometimes I'm overtaking, sometimes I'm being overtaken, but I rarely have to disengage cruise.

EDIT: I also drive with two hands on the wheel, don't listen to the radio, and don't play with my phone.

Agreed, TBH on a quiet 4 line highway I'm in lane 2 to allow the ramp traffic easy on-off. I'll move left to pass if needed, but if there's someone going slower in the far lanes, I'll usually pass on the right to avoid moving over 3 lanes.
