For that matter, Logo of Apple and Audi are two things that are iconic and just floats on top of mind with no effort.

Article has Apple and surprisingly only 20% got it. I think the experiment ran with the hn population would give radically different results, but still, the claim that apple floats to mind without effort is just incompatible with the data as collected

Car brand logos in general are pretty iconic, because you see them all over.

I think it's more than that. They tend to be simple and monochromatic, since they need to be displayed on the car itself - that helps them to be memorable.

My favorites are Infiniti and Toyota.

Tesla comes to mind quickly and sharply - I assume the very positive feeling I associate with it makes it more vibrant to me.

It's funny you mention Audi before the Olympics' logo, though similar.

Not sure what this implies but I couldn't remember what the Audi logo looked like until I saw this post.

Olympics' logo would be interesting to see, because I can't really think of the right color order. I doubt many people can.

I can only remember the apple, cannot recall which side it is bitten.

Lots of people would get the direction wrong.

That was my first thought too.
