in most commutes, if your tailing distance is too much, someone will else will come in front of you.

if you think about the speeds involved, a single additional car in front of you on the freeway (or even any additional cars) adds pretty miniscule time to the total commute.

Let's compare a few situations. In the baseline you're tailing the car in front of you with a focus on not letting anyone cheat and get in front of you, let's say 50 feet away. Your commute is 30 miles, and in this frictionless sphere of traffic you're going 60mph the whole time. You get to work in 30 minutes flat.

In the second scenario you're following the 3-second rule[0]. This would put you ~285 feet behind the car in front of you. Let's say over the course of your commute 20 cars move in front of you. If the average car length is 15 feet, and they all are 50 feet away from each other, when all 20 cars are in place you're a net -(20 * 65) feet away from the original car, or 1300 feet total. At 60 mph that adds ~15 seconds to your total commute time.

Well worth having an easier time avoiding a potential crash IMO! Also has the benefit of helping prevent traffic to begin with[1]

It is not about efficiency or trying not to be slow. I am not bothered how many people cut in line or "cheat".[1]

Someone will always keep cutting into the space. It is impossible to maintain 3 second to the car ahead. First one car will cut in, you make room for them and add 3 second gap the next car will cut in. Maintaining even a 1 second gap is sometimes very hard close to exits.

[1] Personally my driving pattern changed once I switched to driving a hydrogen fuel cell Mirai, slower is better on the mileage and fuel cell owners are very range conscious.

Tell me you're a bad driver without telling me you're a bad driver.

You need to not care about that, and you're actually supposed to let people change lanes into your lane. You're getting into a mental competition with other drivers and sacrificing the safety of yourself and everyone around you.

And if anyone believes that longer following distance causes more traffic, that is also false and the reverse is actually true. It is the poor reaction times of tailgaters that cause traffic slowdowns.

I think that what they're saying is the flow of cars in front of them keeps that distance between them and the 'next car' to a shorter undesirable distance as more cars fill that gap during traffic.

That's fine. You lose like .5 seconds of your life when another car comes in front of you.

It doesn't stop with one, the problem is not someone cut across, the problem is someone always keeps squeezing in the gap. Every time you open a gap, a new car cuts across. How can you maintain any gap in that context ?

As others pointed out - let them. On average all lanes move the same, they might even move away once the lane stops moving. You'll have much worse time rearing a car then letting all those cars in.

I also keep additional distance in traffic to minimize slowdowns/stops, which ultimately actually improves/fixes the flow.

So? Drop back again.

Then another car will do that… and then another… and then another… in the end it becomes way more dangerous.
