Sorry to ruin the party but i never really noticed this until this post. Ive always checked the gas side for a rented with my own eyes. Idea maybe is great but implementation is so so if it’s not immediately obvious for many people

You’re not alone. I point this out to other millenials and gen z all the time and it’s usually the first time they learn about it.

Another signal that the design sucks :)

> 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

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.

Costco and Sam's Club usually have their filling stations set up for one-way traffic, but offhand those are the only ones I've seen that way in US, Canada, Caribbean, and western/central Europe (though the Euro design of filling stations just off the highway encourages one-way traffic, it doesn't mandate it). Haven't driven myself elsewhere.

I agree. As much as people appreciate the factoid, it's not an example of good design. I don't ever recall the arrow being paid attention to until listicles and other blog spam were born. It has all the elements of great clickbait.

I use it regularly when driving an unfamiliar car. I also don’t think it’s ambiguous: it’s a drawing of a gas pump and an arrow telling you where it should be from here, which is a convention from signage the world over. “Paris ->” has never meant “you are this way relative to Paris.” The design I used to find confusing was the controls for periodic windshield wipers: does the width the triangle indicator represent f…

Well, you need to pull up to the side of the gas pump. It's not an "intuition gap". The arrow is ambiguous.

You don't pull up next to Paris, but I would get a chuckle if the icon had a little Eiffel tower instead of a gas pump.

> whats wrong with usb-a? Which way up it should go.

USB-C is better than A in that it works in two orientations instead of one, but the correct answer for connectors should be any orientation — the best connectors are cylindrical connectors: barrel plugs, RCA, BNC, banana, phono, TRS, TRRS, etc. Just make them round .

Well, more like 1.5 orientations because we STILL have devices that only work with the cable in one of two valid orientations.

PS/2, which USB all but replaced, solved this by visually keying one side of the connector as flat.

You've never ruined a PS/2 port by rotating the plug to find the right orientation?

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.

Have you ever tried to use a D-sub connector?

Very asymmetric, impossible to plug in backwards, only one possible orientation.

Still absolutely fucking awful. Same for HDMI, displayport.

The RJ series are the only asymmetric connectors I've use that you can easily get in blind.

Why would you not just always put it on the driver's side, since they're the most likely to be doing the refueling?

What happens when they sell the car in a country that drives on the other side of the road? They would have to move everything around.

If they can switch the steering wheel and all the other stuff around they can switch the orientation of the tank.

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

Our plugin hybrid has both a gas side on the left and electric side on the right. The electric side on the right is helpful in the US to allow parking curbside and charging the vehicle.
