    The gap you leave should be speed-dependent and about 2 seconds to allow for reaction time. Yes, this caps the highway’s capacity to 0.5 cars per second per lane but roads are inherently inefficient.

    • Aye, and 2 seconds is the bare minimum. A company I have worked for wanted 4 seconds between you and the car in front. That always felt a little much, but it definitely helped prevent wrecks.

        In my state, it’s one car length(15-20 feet) for every 10mph. Good luck getting anyone to actually follow it though! Getting on a major highway here is like the Autobahn.

      You should be able to see the tires (generally) of the car ahead of you. That means you can easily / quickly turn out if the car ahead is stalled or something.

      It also means you might not rear end the car ahead of you if someone hits you

      You don’t need to leave a crazy amount of space when stopped at a traffic light, but you still should be leaving some. So if someone rear ends you, it minimizes the risk of your car then smashing into the person in front of you, so it reduces the risk of additional people being involved in an accident.

      At 65mph, you cover two car lengths (~30 ft) in about 1/3 of a second.

      Typically human reaction time for braking is about 1.5 seconds.

      If something went seriously wrong in front of you (like a sideways car, or a hidden obstacle in front of the car in front of you) you would have covered 10 car lengths before your foot touches the brake pedal.

          it’s probably even less, maybe even negligible because of traffic lights at either end: you can’t calculate a single journey because you’re never going to hit the same light exactly the same every time. I have four lights between my house and the freeway, and 7 between the freeway and one of the sites for my job. Each one adds between 0-60 seconds randomly for an average of 6 minutes sitting and waiting per day. I would have to have a commute of like 120 miles of uninterrupted freeway driving for that to matter.

      Then you need to lift off the accellerator, don’t brake check or anything, just slowly slow down.

      If the car behind you won’t give you enough safety margin to maintain a high speed, then your only option to maintain safety is to reduce your speed so that the safety margin they give you is enough to stop in time for an accident.

      Here in Sweden we have plenty of roundabouts, I will use those to also get rid of annoying drivers who just can’t manage their distance, if I have someone like that behind me when I get to a roundabout, I just drive a full lap of the roundabout and let them pass.

      I will allways let these guys past when I can, they are in a rush to their own accident, and I am not, let them pass and and make them stop being my problem, if I can’t find a place to let them pass I will reduce my speed to compensate for their lack of safety margins

      Or you’re in the right hand lane and people are still tailgating you even though you’re going 70mph.

              It’s my opinion that the metric system is superior to the imperial, so we should all be primarily exposed to the superior system. Some may disagree and I won’t claim that I’m objectively correct. No worries if you disagree - regardless of my opinion, the imperial system is what I’ve been exposed to and what I use.

              Alternatively, the statement might be interpreted as “you should be familiar with the metric system even if you reside in a country where it’s not the primary system.” That’s probably less true - while it might behoove one to be familiar with the metric system, I don’t blame the individual for the limitations placed on them by the government, regardless of what’s better.

        Not actually as the “see the tires” rule is fairly good advise. Keep in mind sometimes it is smarter to give a little more space depending on the situation. Think of it as more of a minimum. Also lose most of your speed farther back and then role forward. This allows for recovery time in case of failure or loss of traction.

        Ever heard of clear distance? If you’re at a stop and someone rear ends you and you hit the car in front of you you are at fault and will be held liable.

        As for the rollback in my state they’ll again look at distance. Because if I don’t have enough space to back up because you’re too close you’re once again at fault for not having clear distance.

        On top of all that it helps move traffic along faster. You don’t have to wait as long to accelerate if you maintain distance because you don’t have to wait for the car in front of you to move far enough to start accelerating.

        Getting bumper to bumper has zero benefits outside of the false psychological feeling of forward progress.

      “Only a fool breaks the 2 second rule.”

      I was taught to repeat that phrase, at a normal steady pace, when I saw the back of their car go past something, to use as a marker (a signpost, the end of one of the lines on the road, whatever).

      If you finish the phrase after the front of your car has gone past the same marker, then you don’t have a big enough braking distance and need to ease off a bit.

        My brother in law does this. Gets so close that you can’t see the rear tires of the car ahead, going 80+ mph. He’s been in multiple wrecks, including one where he totaled his custom BMW and almost died. He blamed the other driver (somewhat reasonably, they were drunk, but he was driving like a psycho), and refuses to change any of his driving habits.

        He also used to street race in Florida, with his family in the car. No, they did not consent to it, they’re just too scared of him to say anything.
