Some captchas are getting pretty discriminatory, not everyone lives in the West and can identify the objects they are asking you to. Another recent one sticks out where they asked me to pick a shape as the same number of conoids on screen. If you ask people on a street what a conoids I bet a significant amount will give you blank looks
Also at least now I know some people call those markings crosswalks
Sorry I live in the west, what's a "crosswalk"
Did you mean to say
> not everyone lives in the USA
Other things I don't have a clue about - a fire hydrant, yellow taxis, yellow buses
(Obviously I do, because of American cultural imperialism through things like Captchas which mean the world has to understand American cultural touchstones)
You don't think you could identify yellow buses without cultural knowledge?
I think simply knowing "yellow" and "buses" would suffice.
Does DHL delivery via yellow busses?
Does anyone deliver anything except people via "busses"?
Oh, vans! Of course, who could mistake those?
Well technically anything can be a shuttle because specifically the thing that makes it a shuttle is the operating pattern (repeated point to point service) rather than the machine itself.
Etymology-wise a shuttle was a type of weaving tool which is why the verb shuttle exists, i.e. to rapidly move back and forth across a length (as if you were weaving a thread into a piece of fabric).
So then you got shuttle trains which frequently ran back and forth. And from there other types of shuttle services (shuttle buses, shuttle vans, etc).
And of course eventually the space shuttle being intended to be a launch vehicle designed for shuttle service to and from orbit. (side note but technically if the SpaceX Starship actually achieves it's intended sub-24h turn around it'd be able to qualify as a shuttle provided it ran a fixed point to point route on a regular basis).
