    You can do a while lifetimes work, and yet sometimes it's a tiny action like this which can have the biggest benefit to mankind.

    Just think how many billions of times someone has avoided pulling up to the wrong side of the pump because of this arrow - literal lifetimes of effort saved.

      What's wrong with pulling up to the wrong side of the pump? I do it all the time when the petrol station is busy, just pull the hose over to the other side and fuel the car anyway.
      • CoastalCoder 6 minutes ago
        The hose won't always reach.
        • jstanley 4 minutes ago
          In my experience that's only true in TV adverts from my childhood. I've never had one unable to reach in real life.

      The person (committee?) who came up with USB A needs sanctions.

      And Apple Needs more, for putting power buttons and key ports at that back.

                  I worked in an IT department at one time and encountered USB-A plugs forced into Ethernet ports.

                  It seems so unlikely that I’ve just searched it to see if it’s possible, but am getting no hits.

                  • lefra 18 minutes ago
                    My laptop has one of these ethernet ports that half close when not in use. It doesn't work anymore because someone mistook it for the USB port that's right next to it when distractingly plugging their keyboard in.
                  • fragmede 41 minutes ago
                    no, they definitely fit. They're just awkwardly exactly the right size that while you're trying to plug things in punched over under the desk and crawling around and feeling around the backside; it just yeah.

              And when the port is vertical and you can’t see it?

              I’m surprised how tolerable people seemed to find Apples rear ports.

          • thaumasiotes 1 hour ago
            It's very weird that USB-C solved the problem of "we can't tell which way to insert the plug" by mandating that both orientations should work, as opposed to just making the exterior of the plug as asymmetrical as the interior.
            • dxdm 1 hour ago
              I don't find it weird. Not even having to work out a correct orientation is a great convenience. The micro-USB connection (or is it "min"?), which I need to fiddle with to charge some older gadgets, is a testament to how annoying an "asymetric exterior" plug can still be.
              • lostlogin 1 hour ago
                With micro USB you end up with damaged plugs and ports in my experience.
                • rounce 27 minutes ago
                  Yes, micro USB is far too flimsy for a lot of things it’s used for from what I’ve observed. The connector seems to have a lot of leverage for ripping its tracks off, but often not a great mechanical connection to the board.

              You mean something like HDMI? If you’ve ever tried to plug one of those into the back of a TV, you’ll know it’s still pretty difficult to get it the right way up.

                That's true, but the difficulty in that case comes from being unable to see the hole or fit into the space between the television and the wall.

                For example, plugging an HDMI cable into the back of a monitor involves none of the difficulty of plugging an HDMI cable into the back of a TV, even though the connector and the port are the same in both cases.

          > Which rear facing "key port" on a Mac are you suggesting should be on the front?

          USB.

          I used iMacs, mini and pro machines. Any ports in the front would be nice.

          My m4 mini does have some front ports. It’s less of an issue now with usb-c but the iMac presumably still rear mounts them.

  • wombatpm 3 hours ago
    Which is great for new cars. I drove a 78 Buick Riviera. Friends couldn’t figure out how to fill it up. Because the gas cap was behind the license plate in the back!

      Why didn't they just ask ChatGPT?

      Oh wait.

      • charcircuit 3 hours ago
        For those curious, the first sentence of the response from ChatGPT gets it correct.

        >On a 1978 Buick Riviera, the gas cap is hidden behind a flip-down license plate on the rear bumper.

        • IncRnd 1 hour ago
          That's not what I received from ChatGPT. This is:

          The fuel filler door is on the left side (driver’s side) of the vehicle. Therefore, the little arrow on the dash fuel gauge should point to the left to indicate that.

          (Most Buick Rivieras of that era had the fuel filler on the driver’s side, though official Buick manuals or build sheets from 1978 confirm this location.)

  • schmuckonwheels 2 hours ago
    2020s UX "experts" would bury the entire instrument cluster under a hamburger menu if they could get away with it.

    The fuel gauge would be moved three menus deep and thus impossible to find, then removed in subsequent model years when their telemetry data "proved" no one used it anymore.

    • unglaublich 1 hour ago
      In the end, these engineers' job is make profit for the company. If the customer allows for all this crap, and still buys cars/fridges/tvs with such horrible UX, then it's the way forward.
      • schmuckonwheels 1 hour ago
        >If the customer allows for all this crap

        You imply they ever had a choice.

        Companies like Tesla and Rivian pioneered the trend of bringing webshit-as-an-instrument cluster to the mainstream. Other car companies saw dollar signs, rode their coattails and immediately copied it.

        What is a customer supposed to do? Buy a Mitsubishi Mirage? Build their own instrument cluster?

    • toast0 1 hour ago
      Most of the instrument cluster is superfluous. My 81 Vanagon has only these and it's fine:

      Speedometer (which starts at 10 mph and I've managed to adjust so it's about right at 40ish but reports 70 mph when you're doing 60), odometer (5.1 digits), fuel gauge (non-linear, but consistent, the top half is a lot bigger than the bottom half, no arrow because it hadn't been invented yet). And then some lights: brake warning lamp (but the bulb is burnt out and doesn't seem replacable), high beam indicator, alternator indicator, turn signal indicator (one led for both directions!), low oil pressure indicator, and EGR indicator which really just turns on 10,000 miles after you push the button on the box under the front of the car.

      Don't even need a tach, cause they put one dot on the speedo where you should shift out of first, two dots where you should shift out of second, and three dots where you should shift out of third.

      The gauge lights come on when the headlights are on, so that's a subtle indicator too, I guess.

      Don't really need much more than that. There was an optional clock in my model year, but mine doesn't have one.

      • fragmede 44 minutes ago
        It's all optional if you have enough mechanical empathy. No speedo, oil light, odo, gas gauge. You just get a feel for how fast you're going. You haven't really lived until you've ridden a salvage titled motorcycle with zero instrument cluster across 17 without headlights after the sun's gone down. Sometimes I'm surprised I made it this long.

      It drives usage up! Seriously, I wonder whether this “Make things to annoy people” trend is a normal situation, or an emerging behavior due to our era, and whether it will be solved one day. Example: In 2003 all UX was abominable, programs were ugly and black and white and text and boring, then came the iPhone with the idea to hire designers for apps, it was entirely new and absolutely unseen before. It was necessary during the take off phase of our industry, but are we simply witnessing the regression to normal, with UX being driven by corporate suits?
  • cake-rusk 23 minutes ago
    Cars in India don't have this arrow. The inlet is always on the left (passeger) side. I wonder if there is some regulation governing this.

    Edit: though I have never seen / noticed any cars with the fuel inlet on the driver's side some imported cars may have them.

    I guess this is a first world problem.

      Isnt it that nowadays usually on the side of the driving seat? Or does this apply only to EU vehicles?

      Im not a regular car user, if at all Im renting - but the last 10 times(?) it was always just on the side of the driving seat

      • onion2k 1 hour ago
        Isnt it that nowadays usually on the side of the driving seat? Or does this apply only to EU vehicles?

        That would mean designing two separate entire fuel tank placements, fuel lines, etc for cars that are available both in left- and right-hand drive variants, with different SKUs for each of the parts needed. There is no way a car manufacturer would do that.

      • Sebb767 20 minutes ago
        Usually, it will be where the passenger side is in the cars home market. That is left for Japanese and British vehicles and right for US and German ones.

        Fun fact, for single exhaust cars, the exhaust will usually be on the driver side, in order to route around the fuel tank :-)

      • tripledry 1 hour ago
        Im not aware of such a convention, I'm in the EU and most cars I've owned or driven has it on the opposite side of the driving seat.

        Might just be a coincidence

        • scott_w 1 hour ago
          It’s a coincidence because the UK uses the same cars and ours are mostly on the same side (because we’re right hand drive where you’re left hand drive).
      • apparent 2 hours ago
        I think it depends. Especially with PHEVs, which also have a charge port, whose location is determined by charging infrastructure, and which is not IME on the same side as the gas tank opening.

    Or make it so you can pump on both sides of the car, like we have.
  • mongol 1 hour ago
    Is the side to fill up evenly balanced between cars in average? I imagine there is value to make it close to 50/50 to simplify the logistics at the gas station. I was thinking car manufacturers perhaps had agreed so that some brands do it one way and some do it another
    • LordHeini 1 hour ago
      No the filler placement is sort of a cultural or historical thing.

      Usually European cars have filler on the passenger side while American and Japanese put them on the driver side.

      Afaik passenger side fillers are more safe if you run out of gas and need to fill up from a canister at the side of the road.

      While driver side fillers are more comfortable because you don't have to walk as far to get there.

    • zmgsabst 1 hour ago
      Even if there was a single side for filling, direction of approach being random is enough for 50/50 utilization of the pumps — so I’m not convinced there’s a pressure to spread which side the tank is on.

        > direction of approach being random

        is this specific to a country? I'm not sure I've ever seen a petrol station that wasn't one-way

        • alibarber 48 minutes ago
          Huh, you’ve got me thinking now.

          Here in Finland at least there are a lot of completely unattended pumps that once you exit the road it’s basically just a patch of land and you pull up in whatever direction you want to match the side of your tank to a free pump.

          But in the UK where I’m from and just got back from this is maybe less common.

        • zmgsabst 52 minutes ago
          I’m not sure I’ve ever seen one that was one-way; but my experience is limited to US, MY, TH, and VN.

          In those four at least, traffic can come from either direction so you can have left-handed fills use both sides of a pump.

    On cars without the arrow they often follow the convention where the gas filler handle is depicted on the same side of the gas icon as the filler door is in the car.

    I was like 20 when I learned about this trick. Before then I'd only driven a few vehicles, and I just knew which side of the car the gas tank opening was on. A friend mentioned it when we were going to fill up a car a borrowed car and I asked which side it was on.

    I've since met many adults who were unaware of this trick. It's like the real-world analog of an insufficiently discoverable UI functionality.

    It's a convenient little invention but "the fact that there wasn't a simple way to know which side of a vehicle the gas tank was located on" is not quite true.

    Usually, if the vehicle is of Japanese or British origin, the cap is on the left, otherwise it is on the right.

    Why would you not just always put it on the driver's side, since they're the most likely to be doing the refueling?
    • netsharc 3 hours ago
      And which side is the driver side? Surprise, it depends on the country. And a Japanese car manufacturer will move the driver controls to sell cars in USA/Continental Europe, but flipping everything else will cost more.

      I've driven 2 models of an Italian brand, my previous car had the gas tank on the passenger side, and my current one has it on the driver side. I do wonder why they changed it.

      There's also the issue of pulling to a small road side petrol station, having the fuel door on the passenger side means you don't have to be standing next to the busy road while refuelling.

        Depending on model years, it could have something to do with Fiat merging with Chrysler in 2014. European brands usually have them on the passenger's side, while US brands have them on the driver's side. Maybe that new Fiat was designed in the US.

      • thomassmith65 3 hours ago
        As it should be. If the Globalist cabal had their way, everyone would drive on the same side of the road (like mindless assembly line workers) and traffic signs would be completely standardized, and - yes - the fuel filler would be on the same side of every car (welcome to a monotonous Communist dystopia). They already came for Sweden ('Dagen H' Plan. Do your own research) /s
    • npunt 3 hours ago
      safest place is put it opposite of drivers side, because if you're out of gas on the side of the road and filling it up, you won't be standing right next to freeway traffic. Saab started this.
      • nullhole 2 hours ago
        A linked article agrees:

          "... many European cars have the fuel door located on the passenger side, while many Japanese and American vehicles have the fuel door on the driver side. Both techniques have valid reasons. European automakers place the fuel filler on the passenger side for the sake of safety when a vehicle has run out of fuel and has pulled off onto the shoulder of the road to fill up from a canister. Meanwhile, American OEMs tend to place the fuel door on the driver side of the vehicle for convenience reasons, so that a driver doesn't have to walk around the vehicle when filling up at a gas station."[0]

      • chongli 3 hours ago
        They could design the fuel tank to be symmetrical about the axis parallel to the car’s axels. This would let it be flipped during installation at the factory to have the refueling port facing either side. Then the only difference would be the body panel and little door that covers the gas cap.

      My plug-in hybrid (Audi Q5) has the electric connector on the rear left (driver’s side) and the gasoline inlet on the rear right. I sure plug in way more than fill up.
