What are you talking about? I have never been in a car that did have this little arrow. I just thought it was something you had to know.

(Now I'll have to check my car tomorrow morning to be sure I haven't just been ignoring it all this time.)

It became more common in the late 90s, 2000s. But it used to be a guessing game.

I'd rather all the manufacturers would just agree to a standard and put it one side.

I think the variance on sides is intentional, to balance traffic flow at gas stations.

(Imagine a gas station where most cars use the same entrance and have the tank on the same side. Half of the cars would need to do a U-Turn to use half of the tanks).

It doesn't matter which side the filler opening is on because the pump nozzles reach.

I have never seen anybody reach the hose over their car. Not sure why but I'd feel silly trying it. Like 'look at me I don't know which side I should have put the gas in'.

Wow. So that's what the little arrow is all about????
