Two car lengths on the highway is not enough car lengths to make a meaningful difference in the event of a crash or giving you time to react to an emergency situation up ahead.
That being said, I respect that you leave any car lengths at all and it’s probably better than nothing. Especially since other drivers see any more than that as a challenge to enter that gap. Which is dangerous as shit and they are wrong but won’t learn even after they wreck doing it.
Sometimes all traffic is speeding along, as in 5-10mph over the speed limit, and it looks like pack racing. I keep thinking, all it takes is one distracted driver and it’s a 30 car pile up.
When I was a kid the recommendation was 2 seconds (‘two Mississippi’) but that was when the speed limit was 55 mph on the interstate and cars weren’t as heavy as they are now. Glad to hear they bumped it up.
We also have much better brajes (discs and ABS) and tires (radials) now. So there’s much less stopping distance once you actually hit the brakes. But reaction times are the still the same.
Let them merge. I’d rather give space for those who drive aggressively than be hit. It won’t really affect the time it takes to get from A to B, it reduces stress and accident probability, and I don’t lose points for some race we’re not in. I know some people get mad at passive drivers, but if I’m going around the speed limit in the right lane minding my business, why are you so mad I’m not participating in increasing insurance profits?
If you’re in a country that typically drives on the left, and you’re driving in the far right lane on a three or more lane road, you’re still doing it wrong. That lane is for merging and exiting. The far left is for passing and the center lanes are for cruising. There might also be turn only lanes, which unless you’re turning can be safely ignored, because the only valid reason to be in a turn lane is if you’re turning.
This was my first thought. When I learned how to drive, the rule was one car length per 10 mph. So at highway speeds of 70, that would be 7 car lengths of space to ensure enough distance to safely stop or avoid a collision. I see approximately 0% of people following this rule nowadays, and while I try to maintain it myself, it often results in a stream of vehicles merging in front of me and messing up my distance. Fun times.
In the USA, the lines on a highway are 10 ft long, the spaces between them are 30 ft.
So, a line and a space are about two car lengths. It’s a handy way to judge how close you are to the car ahead. At highway speeds, you want 3-4 lines between you.

I think the safety guidelines are 3 seconds of reaction time which comes out to about 1 car length per 10 MPH of speed.
But yeah, good luck with that because other drivers just see that as space they can merge.

Yep, exactly.
When I notice that ahead, I always slow down a bit to put some good distance between it and myself.

Handy tip:

This is the way
