That's heavily dependent on time and place. I've lived in many different regions, and done a lot of driving in those areas. I've noticed that the tendency to fill in gaps is heavily dependent on local driving culture and the specific demographics on the road at a particular time of day.

That may, to some extent, be an illusion. Some people are infuriated by other drivers they perceive as holding them up -- which often includes people who are "wasting" lane space by letting a gap of thirty car lengths lie unused in front of them. Personally, I only get annoyed with such people when they try to keep other people from filling that gap, because as far as I'm concerned a steady gap (given a steady general traffic speed) creates irregularities in grouping through which ambient traffic can accelerate itself, but people who maintain a huge gap then rush to block out people who want to move into it are increasing the danger of driving and doing nothing to help improve the flow of traffic.
Please see my edit in my original post to clarify what I meant to write. In fact my speed ranges up and down based on the level of congestion, whereas the safe buffer I maintain in front of me remains constant - and by safe I mean long enough that I don't have to use my brakes when traffic slows.
As for my use of "zen", don't read too much into it. It was just a tongue-in-cheek reference to the fact that I stopped trying to fight the flow of traffic and instead simply pass through it as peacefully as possible.
>That's heavily dependent on time and place.
My observations are limited to highways in Ontario, Quebec, New York State, Pennsylvania, and Massachusetts.

Hey, man, you're welcome to it. Blocking another driver from filling the gap would mean accelerating to close it, which kind of defeats the purpose of maintaining it.
The original comment, for those that don't get it yet, was a stab at apotheon's comment. It was an attempt to avoid the argument of "what is Zen" before it gets out of hand, as it's been known to do on other sites.
If you're curious, an example: http://zenhabits.net/2007/01/why-zen-habits/#comments
1. Are you driving faster than the speed limit? Coast. If not … 2. Can you see more brake lights (that is, cars with brake lights on) ahead of you than the number of lanes traveling in your direction? Coast. If there are more lanes than cars with brake lights … 3. Is the buffer between your car and the car in front of you getting smaller / staying the same? Coast. If the distance is getting larger, you can accelerate.
So, essentially, the only time you get to accelerate is when you're below the speed limit, there aren't many cars braking in front of you (in any lane), and the gap in front of you is getting larger.
And here (below this) was the copy I'd worked up for the page. I was calling the approach "coasty," and was applying some game design theory to it, so if there are any "game" references in the copy below, that's what they're referencing.
========
The goal of Coasty is to consume less gas, to drive more safely, to get to your destination in about the same amount of time as you would otherwise, and to have more fun while driving.
Consume Less Gas:
Almost every time you brake, you’re wasting gas. You had to use gas to accelerate your vehicle, and you’re now intentionally slowing the car down. You’ll then need to accelerate again, to get back up to speed. You're doing twice the work, for the same amount of output. By braking less often, you end up accelerating less often, getting more miles-per-gallon and saving money (both in gasoline and engine wear). (Obviously, if you’re braking because of a stoplight / stop sign, this doesn’t apply.)
Drive More Safely:
When you're driving aggressively, driving closely to the car in front of you, and focusing on getting where you’re going as quickly as possible, the more likely you are to get in an accident. The amount of space and time you have to make a decision (and execute it) is determined by the amount of space your car has in front of you, and the speed at which you’re traveling. It’s counter-intuitive, but by focusing on braking-and-accelerating as little as possible (and by coasting as much as possible), you end up with a larger buffer in front of you, and you generally enter that buffer at a slower speed.
Get To Your Destination In About The Same Amount of Time:
It’s not fun to be late. And — let’s be honest — you probably aren’t going to stick with a new approach to driving if it compromises your ability to get somewhere on time. But with this approach, you’re reaching each “micro destination” (that spot further down the highway, that exit ramp, that streetlight) only a few seconds behind where you’d be otherwise. In some cases, you'll get there even faster, as you might end up approaching a stoplight while coasting, as it turns green, rather than approaching it, stopping, waiting, and then accelerating again from a stop, while the guy in the lane next to you cruises through at 10 miles an hour.
Have More Fun While Driving:
This approach actually makes driving fun, as the goal shifts away from “getting where I’m going as fast as I can and who do these jerks think they are, getting in my way?!?!” to one of a game mindset, where you’re trying to follow the rules, seeing how far you can go without braking, and seeing how much your fellow drivers have to speed up and slow down while you’re coasting along.
As a side benefit, creating a larger buffer and then eating it up enables the cars behind you to have a smoother trip at a more constant speed, where they aren’t having to brake as much, either, and dissolves the slow-down-then-speed-up-then-slow-down-again rubber-band traffic cycle.
The main benefit for me, and one you don't mention, is safety. Knowing I have actual time to react in an emergency instead of being stuck with brake hard and pray I think really calms my subconscious.
The rule is simple and works for any traveling speed: pick any arbitrary mark on the road, watch as the car in front of you passes it, and count 3 seconds. You want at the very minimum, 3 seconds to pass before you pass that same mark.
This not only has the advantages described by the OP (he's definitely following it, if not calling it by name), but one thing he didn't mention is that it can save your life.
Why do car "pile ups" exist? It's because someone was driving along just fine, when suddenly they come to a crashing hault (at 70+MPH), and all of the tailgators behind them are not physically capable of reacting to the situation in time. SMASH! You're fucked.
7 seconds at highway speeds can be over 200 meters.
I'm all for safety, but that is excessive.
PS: Thinking you have a 2+ second reaction time helps to cover when you are not directly looking at the car ahead of you. The less of that cushion you have the more you need to focus on the car in front of you.
edit: spelling
I've driven like the article suggests on Rt. 128 and it totally works. My lane ended up moving smoothly (albeit at a reduced speed; I still can't go any faster than the average speed of the cars in front of me), and nobody cut in front of me.
However, drivers on Rt. 2 are routinely crazy. There've been times I've been going about 70 in a 45 zone, with a guy on my tail, then he'll pop out from behind me, pass me at about 90 mph, cut right in front, and then tailgate the person in front of me until he does the same stunt. Luckily traffic on Rt. 2 is light enough that this doesn't cause many jams, but it does cause its fair share of accidents.
Then there's the Rt. 2/3/16 intersection by Alewife, where it is customary for about 5-10 cars to run the red light before somebody finally stops.
I figure if my method can work here, it can work anywhere. :)
I tend to leave about twice the gap of other vehicles on the motorway, still strictly not the full stopping distance (but having been a motorcyclist I feel I read ahead well). I always find that people invade my stopping/slowing space; then one drops back and another car is in there.
I'm in the UK.
When I do this before stoplights I sometimes catch a green light with road to spare, and I'm able to avoid stopping at all. This helps me somewhat, but as a side effect it helps the traffic behind me a lot more.
I'll try to do this more often. Keeping in neutral is easier then trying to compute an optimum speed, and it'll help a lot with the consumption too.
In any case, you're not really saving any gas over coasting in drive or, alternately, setting the cruise control.
Instead of competing to get ahead the game has changed to strategising to keep the traffic moving. It's beautiful and fun and transforms the whole driving experience, very zen.
Heh, you didn't happen to learn to drive in, say, Massachusetts did you? It's called the "rear view mirror", but I've found that due to the accent, many people here in Boston have always thought it was the "review mirror".
I picked it up from truckers, who uniformly take this strategy.
While there are some courteous and sensible UK truckers, most of them seem to be driving right up against their speed limiters, and will tailgate then overtake anyone in front who dares travel 1mph slower than them - even if this involves attempting to overtake while going uphill, causing a wall of congestion on an otherwise free-flowing motorway.
I also fond that places with a higher percentage of auto drivers are heavier on the heavy traffic scooch-and-brake.
People don't do that in a manual because it's not fun.
*In Italy people drive mostly manuals. They also drive like suicidal grandmas in fast forward.
On long driving trips through mixed traffic, I have made several observations, some obvious and some surprising:
* Driving in congestion is no longer stressful. It just isn't. (Hence the "zen".)
* Dramatically improved fuel economy.
* It's possible to drive through even wildly erratic traffic (swinging from 100 km/h to 20 km/h) without ever touching the brakes. It becomes a kind of game. Manual transmission helps.
* Some other drivers seem to figure out what I'm doing, and they fall into place behind me at a reasonable distance. I've had people follow me for hundreds of kilometres this way.
* Even though you'd assume leaving a huge gap in front is an invitation for other motorists to cut ahead, they rarely do - especially in congestion. If they do, I just let them race up to the front of the gap and then fall back by a single car length to restore the same gap.
I absolutely swear by this driving method. It's easier on the car, easier on the heart, and even serves to create a bubble of calm around you in an otherwise turbulent flow of traffic.

[1] Edit to qualify "drive at a constant speed". As I noted later, my speed ranges dramatically based on the congestion level - what remains more or less constant is the safe opening in front of me. Sorry for any confusion with my original choice of words.
