I assume non-downtown US residents are still significantly more aware of the term, what it is, and what it looks like.
I'd heard it in films before captcha, but had to guess it's the zebra crossing looking (the meaning is different though, I understand) things. Now it's just something I'm familiar with because of captcha, even more so 'parking meters'. Which is just weird, why do I have to learn something mundane about a specific country in order to prove I'm human and allowed to use a global website?
