    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.

    Two car lengths? You absolute madman! That’s positively grotesque!

    For the purposes of this comment, I’m assuming that cars are about fifty feet long.

    Intelligent people leave a space of about two cars ahead of them on the freeway.

    Stupid people think that space must be for them.

        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.

      I was driving in slowish freeway traffic in Detroit and the guy behind me plowed right into me, didn’t even slow down, didn’t even look away. He sort of bounced off of me, pulled onto the shoulder, and squeeled off while I had to find some sketchy spot to stop and make sure my bumper wasn’t dragging too much.

      A person I was visiting there in Detroit told me that insurance wasn’t required so many people run off rather than risk getting blamed and the cops wouldn’t even bother with a report.

        Insurance is required in all of Michigan, with fines, license suspension, and jail all possible for not having it. With Michigan’s no-fault insurance we have some of the highest rates in the country in Detroit—especially relative to income—and almost no viable alternative to owning a car.

        That said, as a native Detroiter I feel safer in Detroit driving around other Detroiters, the suburbanites and out of state folks are always in the way.

          I thought I heard that insurance laws changed maybe since then or around that time and there was a reason for a lot of hit and runs. I don’t know, but that was my experience a while ago. The weird part was mostly how the dude had no visible reaction at all except to take off, which probably could’ve been anywhere.

          As an out of towner I did have trouble with the short on ramps. I wasn’t sure how to get into a rhythm because there was no place to get up to speed. I didn’t like feeling like I had to shove my way in and it was hard to tell how to let others in safely. I suppose you just know those things when you live there long enough.

            Those are some of the first below-grade expressways built in the country, so the shorter on ramps are from an era with fewer and slower cars, and there isn’t space to lengthen them. The law only changed to stop the insurance companies from using zip codes to determine rates, and reduced the maximum payout for healthcare related costs from a crash, with the aim of lowering costs, but of course the insurance companies worked around it.

    When I leave two car lengths, four cars will go into it, and at least one of their drivers will throw a half empty beer can at me.

    The simplified distance rule we learn in europe is: half your speed (km/h) in meters or as an equation, v/2000. E.g. you drive 120km/h, keep 60m distance.

        That’s the underlying reason to keep distance ofc. The rule of thumb gives you an easy to calculate solution to how far that approximately is.

          I don’t need math for this. Once you have a feel for your car you can just visually gauge it in an instant.

            Judging by how close people follow me on the Interstate, I have a feeling most drivers think this but only a small percentage can do it effectively.

            And judging by how close 9 out of 10 pickup truck drivers follow tailgate me on the interstate even when I am doing 10-15 over, I have a feeling most don’t care and would prefer to run me over in their lifted Rams and SuperDutys.

      In the US, usually it’s one car length per 10mph.

      Probably not much more intuitive than yours, but less math required on the fly.

        Tbh the math required is pretty similar, I just divide the speed by 2 and am done.

          That’s very reasonable if you’re accustomed to operating in metric … Which we all should be, but here we are.

              Ah, that could be interpreted at least two different ways. I have a suspicion of how this conversation will go, but I’m interested to find out.

              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.

              If you have a third interpretation, it’s probably not what I meant, but I would be interested in hearing it.

      In France the way we learned is (for the highway at least)

      • 110km/h: 5 small markings between you and the other car
      • 130km/h: 2 large markings

      I’ve always preferred the 2 second rule. You don’t need to do distance math in your head, just find a tree and count the time it takes to get from their car to yours.

    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.

    I always heard “2 seconds of space” which is a lot more than a few car lengths, to give yourself time to react to both what’s in front of you and to the sides, and account for if their brakes perform better than yours. Two seconds of distance is a lot, though, and kind of impractical in traffic.

      The recommendation changed from car lengths to seconds decades ago, but wasn’t well communicated fwict. I learned car lengths from my dad and then seconds when I got my motorcycle endorsement.

      If everyone were leaving 2 seconds of space, it also reduces stop and go traffic that is caused, or at least exacerbated, by the traffic wave phenomenon. But that’s even less well socialized.
