I will never understand why this is so rage-inducing for people.
Changing lanes is a necessary part of navigating, even during busy traffic. People on an on-ramp will need to get in front of somebody. People needing to move back to the right because their exist is coming up will need to get in front of somebody.
Your lane is not a birth right. Let people merge.
> you slow down to maintain a safe following distance, another car sees a gap and changes lanes in front of you. Repeat for your entire commute.
This happens because literally everyone is tailgating each other so hard that the gap in front of you is the only gap that exists for people to change lanes to either get on or off the highway.
I think if you reflect a bit you'll find you are being the same kind of person as them, if you are getting angry that you have to slow down and give up space for someone else. I understand some people can be aggressive though, that can be frustrating regardless of the outcome.
We're not talking about where they're changing lanes to take the next exit. We're talking about where your lane happens to be moving faster, so they merge in front of you in an unsafe way to take advantage of that and just stay there. Why should you be expected to give them space, as you suggest? How is that fair, that they should get to their destination faster instead of you? Do you not see how that's going to rightfully make someone angry? When they should be waiting for a safe space to open up, rather than forcing you to slow down to create one?
that's hardly safe when it's already tight with a safety buffer as it is.
provided they use a signal as required by law and taught in the drivers handbook, they'd likely be let into the new lane without any judgement.

A third perspective may be "game theory." I think the Prisoner's Dilemma [0] could explain some aspects of the physical/mental problem. In the set below, Driver A's strategy isn't dependent on a singular predictable Driver B but all drivers that may perform the role of Driver B during the course of a commute.
Agent Cooperate Defect
Driver A leaves space doesn't
Driver B^n merge stay
I conjecture that this is a collective action problem and that above a certain traffic saturation point there must be a social taboo against changing lanes.
This is not to claim that individual perspective shifting is not important. I am reminded of Foster Wallace's Kenyon address "This is Water," [1] quoted below. However, the task of changing individual perspectives is vastly higher energy than the creation of a social taboo, which is why purity codes and other social inhibitors are so prevalent.
If I choose to think this way in a store and on the freeway, fine. Lots of us
do. Except thinking this way tends to be so easy and automatic that it
doesn’t have to be a choice. It is my natural default setting. [...]
The thing is that, of course, there are totally different ways to think about
these kinds of situations. [...] [Maybe] the Hummer that just cut me off is
maybe being driven by a father whose little child is hurt or sick in the seat
next to him, and he’s trying to get this kid to the hospital, and he’s in a
bigger, more legitimate hurry than I am: it is actually I who am in HIS way.
Now you've just created a shockwave traffic jam.
> someone is taking your safety buffer as their opportunity to travel faster
Nobody is 'taking' something; we're all just sharing the road, and at little cost. People change lanes for many reasons, and sometimes to pass someone else and travel faster. That's what the left lane (if we're talking about the US) is for.
> results in you having to travel slower and slower to maintain the gap that is constantly consumed,
I understand the theory but that hasn't happened in my experience.
And even if five or ten cars got in front of you, how much distance is that? A random Internet site says the average midsize car is 16 feet; add 220 ft safe driving distance at 75 mph (says another random website), so let's say 240 ft per car x 10 cars is 2400 ft. In that extreme circumstance, it will cost you ~30 seconds.
It's self-fulfilling: If you act aggressively toward other drivers, they will respond in kind. If you treat them respectfully and politely, they act the same way toward you. People behave well and kindly, naturally. We are social creatures.
It's the people who aggressively slide right over just a few feet in front of me (cutting off nearly all of my safety buffer) without so much as a signal that really drive me nuts.
So for the love of gods, if you're merging, even if you signal, match speeds for merging. If you're too slow to match speed, then suck it up buttercup, and hang out in the right lane until there's an opening.
I've had times where the right lane ends up being the fastest. On I-5 near Woodburn, OR, it's 3 lanes. So many drivers, including truckers, will often stay out of the right lane entirely to avoid being caught up in traffic coming on/off. Meanwhile, the left lane is going 5 mph under the limit because there's a left-lane camper somewhere miles ahead. So I can fly past everybody in the right lane because there's actually barely any traffic coming on/off and everybody is avoiding the right lane for no reason at all.
What I really hate, however, is that plenty of people will cruise in the center lane but still not leave a decent gap between them and the car in front. They effectively turn a three lane freeway into two one-lane freeways by hobbling the ability of anyone else to switch lanes. The freeway moves way smoother when there is a modest, predictable speed differential between each lane so that people can find their way into the next lane over without having to force the issue.
At 30 mph how much later will you be? 37 seconds.
I’ll take that trade.
At over 100 km/h that would be ideally 5m for a car and 70m for a safe distance between each one so 7,5km, which is 4.5 minutes at 100 km/h or 9 minutes at 30 mph.
You're ascribing motive where you have no data to do so.
> travel slower and slower
Roads near capacity slow down. This capacity surge is typically highly predictable.
> tragedy of the commons style, by opportunists.
People can only drive one car. They cannot drive two at the same time to get there twice as fast. I don't think this logic applies.
This exemplifies the problem with America. People will cut off their own welfare to make sure their neighbor doesn't get any either.
All of the people tailgating are contributing to the congestion.
I don't drive as often as I used to, but on I-76 coming into or out of Philadelphia, traffic gets snarled and becomes stop-and-go. Every now and then, someone next to me appears to have the same understanding of fluid dynamics as I do, and we build up enough of a buffer that we are able to eliminate the stop-and-go, even if it means rolling at 5mph with a big gap between us and the cars in front of us.
There's no good way to communicate what we're doing, even to each other. But I like to think that when this happens, it has a positive effect that ripples out for miles.
Yup. The brake pedal is an evil device that converts cash into brake dust and waste heat. Before I got an EV, I always drove in such a way to use the pedal as little as possible. As a result, in my previous car that was stickered at 24 mpg city/30 mpg highway, I averaged 32 mpg. I don't even drive slow, I just drive smoothly. If your average speed is going to be 5 mph, then you'll get much better economy driving a constant 5 mph than your speed being a sine wave between 0 and 10 mph.
Good driving instructors make you aware of that early on, at least mine did.
I'm not saying that I'm a good driver, because I make mistakes like any other driver out-there, it's just that I oftentimes go with the "maximize the flow" thing instead of just following my individual "well-being" as a driver as a result of what my driver instructor told me some years ago.
Adam Something has a video responding to it that's worth watching too: https://www.youtube.com/watch?v=oafm733nI6U
The train of tought goes something like this. You want to get to your destination quickly as just like everyone else and are doing everything correctly, but the assholes exploit that safety distance as a gap available for them to switch into and repeatedly forcing you to break to maintain a safe distance. Oh and the even less rational people think everyone overtaking them has stolen their rat race position.
Leaving a keeping a safe distance feels unsafe since other drivers will squeeze into it. Subjectively it feels safer to close the distance, but the numbers don't lie. Tailgating kills.
It's especially not people trying to get off the highway because then they leave and you can catch back up to where you originally were.
Putting my armchair psychoanalyst hat on: I think American society embeds a need to be the "winner", and are you winning if end up behind another driver who's contending for "your" spot?
If you've driven elsewhere for a while, you start noticing subtle driver differences, such as drivers who want to merge into your (slower) lane never braking to merge behind you and always accelerating to do so, even when you're at the tail end of a vehicle chain in your lane.
Comparing to the experience of being a passenger on a bike in Saigon, the level of cooperation there is way higher, possibly due to a sort of necessity. I had this feeling while observing traffic there, that, while the latency and throughput of the roads during high traffic times are still kinda awful, at least for bikes there's a slow continuous progress that simply wouldn't exist without cooperation.
Funnily enough, my experience driving in Los Angeles was distinctly not terrible. Traffic was usually good enough to drive in, though there was very little regard for the speed limit on the freeways! I suspect I may have just been lucky to miss the worst of the traffic.
This ensures that
a) I do not cut anyone off accidentally, and minimize the amount of stress in my immediate part of the universe
b) I will (most likely) have plenty of room behind me after I change lanes, reducing chances of anyone else running up on me
c) If there's noticeable traffic, the time I spend signaling and waiting for the person to move slightly ahead of me gives plenty of warning to the people _behind_ them that I'm about to enter the lane.
Ultimately, yes, of course in principle you're right, when I change lanes, I enter the lane in front of someone.... but I _can_ control whether I enter as far as possible ahead of them.
And in inclement conditions, it can make the difference between losing control of your vehicle or not. When you brake, you decrease your steering ability in most cars. Fine when its calm and sunny in CA, not so much when it's icing over near Ashland OR on the pass.
My point is, it feels safer and easier to aim to enter a new lane with the aim of "following" someone, rather than trying to rush in "ahead" of someone. But maybe it's just me.
It doesn't even have to be real. There's huge room for miscommunication. Unpredictable movements and perceived aggression, or unwillingness to be considerate to other drivers on the road, there's a whole wealth of information being processed, regardless of how little is actually real.
Now add the total lack of accountability for the driver's emotional state (don't you love yelling at other drivers, completely free of judgement?), and you can see how things spiral into road rage so relatively easily, even if everyone involved is normally a pretty chill, rational person.
If you're tailgating or brake-checking, or being inattentive and sloppy, you're basically threatening people's lives with a few tons of high speed metal, even if you don't intend that at all.
Ideally, the rules of the road are meant to reinforce a mutual understanding of the game being played. Behavior occurring when expected, proper signaling, observing limits, and making the effort to communicate where possible is a signal that you and the other driver are both operating by the same set of rules, giving you both confidence that neither of you are going to be a danger.
I've seen little "cute" exceptions where locals develop a subculture of dangerous assumptions and then get aggravated when someone from out of town doesn't immediately get it. There are other areas where aggression and what amounts to flagrant disrespect are the norm, so you've always gotta be adaptive, but ideally you get people conspicuously following the same set of rules as a sort of game theoretic optimal strategy for driving.
It's simply not possible to merge during heavy traffic without eating into someone's safe following distance.
