Anybody else get confused by whether the arrow represents where the car should be or the pump?

Yeah, it's a bit counter-intuitive.

No

I think this is the source of me misinterpreting the symbol a few times, so yes.

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

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.

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 :-)

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

Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by scott_w on Friday January 02, 2026 @02:21AM (#46462304)
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).
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by apparent on Friday January 02, 2026 @01:56AM (#46462144)
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.
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by dmead on Friday January 02, 2026 @03:43AM (#46462726)
My phev has charging and gas on the same side. I'm american

My PHEV has charging and fuel ports on opposite sides. Volvo XC60.

I do. It is not obvious in any case
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by sublinear on Friday January 02, 2026 @12:52AM (#46461839)
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.

Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by gk1 on Friday January 02, 2026 @01:09AM (#46461921)
I actually use it all the time when driving a rental.
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by mhdhn on Friday January 02, 2026 @01:39AM (#46462070)
I use it all the time because I switch between a lot of different cars a lot, and my memory is not that great.
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by jquery on Friday January 02, 2026 @02:09AM (#46462214)
That isn’t in conflict with it being bad design.
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by mschild on Friday January 02, 2026 @03:51AM (#46462793)
True. Though im unsure of what would be a better one. Doesnt get much simpler than an arrow.

Id think that for a car you own you wouldnt need it after the first few times though.

Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by chillstreem on Friday January 02, 2026 @04:49AM (#46463182)
a better solution would have been to have an industry wide standard icon for the fuel inlet and then an arrow would point on which side of the vehicle it is. The way it is now with the pump icon really can be confusing. If the arrow is pointing right, it seems to be suggesting the driver should go to the right of the pump which is obviously wrong.

I like the way EVs have the squiggly hose icon and that tells you everyting.it doesn't depict the charger station, but the plug point on the vehicle.

“Directions are ambiguous, when somebody says turn right, I grab the wheel by the bottom and move the hand to the right”

*Technically* it could be less ambiguous, but actually it is good enough.

If memorising this is hard, not a big problem, parking next to fuel pump twice is not that huge of a damage.

Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by rtgfhyuj on Saturday January 03, 2026 @01:57PM (#46480201)
in the absence of industry wide standards, this is an ingenious design, 100% best thing possible
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by mayneack on Friday January 02, 2026 @01:40AM (#46462073)
I use it regularly
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by jquery on Friday January 02, 2026 @02:08AM (#46462210)
It’s terrible design. Until I encountered one of these listicles I had no idea what that arrow was.
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by icambron on Friday January 02, 2026 @09:21AM (#46464983)
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 frequency or period? I eventually just managed to memorize that it means frequency because you get more wiping as you turn it “up”. I don’t think anyone else ever found this ambiguous; we all have our little intuition gaps, I guess.

Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by sublinear on Friday January 02, 2026 @12:36PM (#46467215)
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.

Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by rtgfhyuj on Saturday January 03, 2026 @01:58PM (#46480212)
nah, the pump is visibly physically, dont need an arroq thats idiotic
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by maxerickson on Friday January 02, 2026 @07:57PM (#46471562)
Baader–Meinhof phenomenon.

The fact that it is consistent across vehicles sort of mitigates the problems with it. "Arrow points at fuel door" is not actually hard to remember.

Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by Taek on Friday January 02, 2026 @06:11AM (#46463664)
The arrow indicates where the hole is.
Re:James Moylan, Engineer Who Designed Gas Tank Arrow Indica... by quickthrowman on Saturday January 03, 2026 @10:39AM (#46477869)
It points towards both the gas pump and also the side of the car that has the fuel filler, it’s impossible to confuse.
