I don't think that going down the road counting one thousand one, one thousand two, etc. and restart when another car pulls in front of you is easier than to estimate a car length behind a vehicle. in any event, there will not be any precision into any method is used to determine distance.

Many people have difficulty estimating distances. And what "is" a car length? Is it a vw bug or a pickup or a sedan or a station wagon? Counting to three seconds takes those arguments out of the equation.

My statement does exactly that! Faster you drive there will be more distance between you. Two seconds at 90 the distance between will be greater than at 55.
I stand by Mr Purvis' drivers ed recommendations many years later.
Exactly...I knew someone would question this, not thinking it through! I drove to drivers ed, but was not old enough to have a license yet. D's ed was fun, and I did learn from the experience.

The data shows that you are more likely to Be IN A COLLISION if driving at the much slower speed. It does NOT show that the slow driving person is the CAUSE of the collision. Per the data from the NHTSA study, the CAUSE of that collision is most likely because the other driver was distracted, speeding, tailgating, not correctly judging the amount of space, overcorrecting, falling asleep, etc.
You are still focused on finding fault. I'm talking about eliminating accidents. I don't care about "fault" I want to eliminate crashes.

Speed certainly isn't the only reason for crashes but it's been decades where it has been beaten into the American conscious that "speed kills", so not surprising, no one "claimed" is was low speed.
Increase space sounds good but in foggy conditions, if you slow down more than most, that means you have more interactions with cars passing you (or creating long lines of closely spaced cars behind you). It's not a simple problem for a human driver to solve but if you are doing 25mph in a 70mph zone because of visibility, you should be getting off the road entirely (short of an emergency). Adaptive speed control that can see thru fog and react more quickly is our best bet for solving low visibility issues.

This is 1 reason I always say the best vehicle for first car is a regular cab small pickup with 4 cyl, manual transmission. The low power reduces chance of showing off. Manual transmission mean pay more attention to driving. The frame IMHO is better when (not if) they wreck.
And most important; Think back, every time you got in trouble, or should of got in trouble, there was 3-4 friends in the car with you. The little cab reduces that chance.

Again, the cause is tailgating. Had that person left more room between cars, there wouldn't have been a collision. People drive at different speeds - it's not for one person to "punish" others by tailgating them until they move out of the way. If traffic is so congested that you can not safely go around the slow driver, then you need to slow down accordingly. If traffic is such that you can safely go around the slow driver then you should do so. There is no legitimate reason for tailgating.
Keeping a safe distance from the car in front of you is Driving 101.

Actually, this data was based on a project where the NHTSA went out to the accidents with the police and questioned the drivers at the scene and then compared those statements to the cars' data and the skidmarks, damage to the cars, etc.
As such, the report shows that no one stated "he was driving too slow" as the cause of the accident. Yet many many people stated they were distracted, speeding, tailgating, or had fallen asleep, etc. and that's why they hit the other car.
So your argument doesn't hold water.
In a 100 car pileup, it does not mean 99 people were going one faster speed and one was going much slower. That is your bias showing. All it means is that 99 people failed to not hit another car.
It could have been caused because there was a large piece of debris in the roadway and the first car swerved to avoid it thereby causing the cars around it to swerve and all the cars behind were following too close to stop in time.
It could be that one person was driving significantly faster than everyone else and didn't see the car ahead due to fog and hit it causing a chain reaction.
It could be that someone was trying to read a report on the way to work while driving and swerved to make their accident causing a chain reaction.
The idea that all (or even a significant number) of these pile ups were caused because one person chose to drive too slow is simply trying to justify speeding - and it doesn't work.
In reality, the best way to avoid a pile up is to increase the space between cars. If the car in front of you swerves, slows down, or farts, you should be far enough back to not have to slam on your brakes. And if you avoid hitting them and take a huge sigh of relief, you were still too close.
That's why the three second rules works - because the faster you are going the more room between you and the car in front of you. Because the higher speed requires a greater stopping distance. But most people maintain one car length or less between them and the car in front of them at any speed - because heaven forbid someone is allowed to move over in front of them. Heck, they might have to drop their speed from 70 to 67 for a minute in order to reestablish that space and that is unacceptable.

I don't think that '1 car length per 10 mph' has been a recommendation for a long time. Mostly I have heard spacing given in seconds, not distance. And most do not mention that if you are following a car that can stop faster than you, you need to add time that you would be moving to the 2 seconds it takes you to react. In other words, a car 3 seconds behind a TT is likely not tailgating, but the TV pulling a TT 3 seconds behind the car probably is.
