    It’s a nice thought, but it has so many modifiers it’s pretty much worthless. Everything from road conditions, to time of day or night, to the size and weight and type of vehicle you are driving, to how old you are affects stopping distance and the interval you should be leaving.

    Remember children - Driving should never be “relaxing.” It’s real work and demands your total concentration to protect yourself and everyone around you. So put the phone down and even turn off the radio. Put your head on a swivel like a fighter pilot. And have an escape plan for every inch you drive.

      I don’t know why you are being downvoted since the distance from other cars should absolutely reflect the current conditions. I also agree that to drivers need to proactively look for possible collisions in mirrors and blind spots, though they should be generally calm and patient when driving.

      “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.

      At a stop? Who cares? Can’t being closer together at a stop light at least help with intersections? I guess it depends on the city.

      If you’re driving a manual and you roll back on a stop, you shouldn’t be driving a manual. Unless you live in like San Francisco I guess? In the Appalachian region, cops will stop you for rolling back.

        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.

        Terrible, terrible advice. That leaves a full car-length of empty pavement with the driver sight-lines of modern SUV and crossover designs. Pickup trucks are worse; I’ve seen pickup truck drivers stop a full 30 feet back. It wastes huge amounts of space on the street, and causes traffic congestion. On the other side of the coin, van and bus drivers can still get right up on your ass when following this advice.

          I hate breathing in pollution so I keep a car’s length between me and the next car at traffic lights. Cars themselves are a huge storming waste of space and I hate being in or around cars with all my heart and soul so if I make traffic worse then I will consider it a passive form of protesting against car dependency

        What it looks like:

        1000005472

        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.

          I feel like it really isn’t your fault if you role back 6 inches and hit them. If you were to roll back 4 feet it would be different but in this case you can’t control something so small.

        It depends.

        On a well developed well maintained “freeway” with multiple lanes, shoulders for break downs, gentle curves, et cetera it’s common. 3 car lengths is more common here I think.

        That said, on a “highway” (interstate?) without everything listed above I aim for 2 seconds, which is about 60 metres at highway speed.

      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

      It’s in case some jackass on their phone rear ends you, if you’re too close you’ll get pushed into the car in front of you. IIRC you can be liable for the damages to the car in front of you while stopped if a multiple car accident happens.

      Cars are getting bigger, but people aren’t getting taller (as fast). Little granny can barely see her hood over the steering wheel so she needs to leave 2.75 miles of space between her and the car in front.

      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.

      That’s a thing? Seems pretty silly to me. You need space but not that much.

      What annoys me here is that people will enter the intersection before traffic on the other side has a chance to clear thus blocking the road when the light changes.

      I also don’t think the people who speed though the turn light. The light turns green and I have to sit and wait for traffic to clear

    My car’s “smart cruise control” leaves what seems to be around a car length for every 10 mph, which is what I remember hearing in driving school. Feels a bit excessive in practice, but I also never feel like I’m being an asshole so I’m okay with it.

      I was rear ended, HARD once. That distance gave me the space to control both my vehicle, and the one that hit me. It turned a potential multi car, multi lane pileup into a 2 vehicle wreck, either 1 more dinged car.

      The space isn’t for the 99.999% of the time, but that 0.001% OH FUCK time.

        I almost had that happen to me a year ago. Traffic had stopped on the interstate and I hear skrrt, skrrt, skrrt, skrrt getting closer and closer to me. I looked up in my mirror and see a Silverado rapidly closing the distance and thought “god damn it”. I fortunately left enough room between me and the car in front of me that I was able to give him some more space and turned a full on collision into a tap that didn’t do any damage. Pretty sure my foot was actually off the brake when he hit me and that helped absorb some of it as well. I was still pretty pissed though because I had more than enough time to think about all these things and consider moving onto the shoulder but I thought he would do that instead and still hit me with how fast he was going. Being an idiot, he did not and hit me anyway.

    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.

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

      Some people are unnecessarily aggressive on the road. Probably because they have unresolved emotional issues and take it out on other drivers. At least that’s what I tell myself.

      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 to that the safety margin they five 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

    I leave enough room for me to have time to react and give the person behind me enough time to react to my breaking. Because most people drive way too close to avoid a rear-end collision if I have to slam my breaks for an emergency. Sometimes that means I’m 4, 5 or 6 car lengths away from the car in front of me, but that has the added benefit of pissing off tailgators who will almost immediately choose to pass me which works out great for me. The less space the person behind gives, the more space I leave between me and the person in front.
