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.
