They suck in Canada

???

In Turkey in most places a ton of them don't work so it isn't very helpful.

Calgary, Canada has these in places. They are super helpful!

What are the blue lights 4?

My cousin sells those they are so useful

Everywhere in France (But they usually don't work 100% right)

I lived in Switzerland, and it was amazing that they had these.
I'm now in Colombia. Colombia. And they have these.
I think that classifies them as common

I'm color blind so this is useless to me. Apparently its rare for girls to be color blind. But its still cool.

Portland, OR airport has them

Same in Portugal, Spain and probably 99% of Europe... they're almost 100% accurate, except when some dildo parks a Smart or a bike.

There's a bunch of places in Maryland that have those

Surely you can usually tell if a space is taken or not...

they are literately every where (even nope land Australia's airports and shopping malls where i live).

We have it too in Spain, didn't know it was that uncommon

By the way, blue ones are for people who has discapacities. Sorry for my bad English :p
