Being an African born & bred in Nigeria, I particularly find this appalling. Captcha usually asks users to identify fire hydrants, crosswalks & other objects with design patterns that are not common here, in everyday living. There's a big question on whether these approaches work well for onboarding the next billion users to the internet, especially since the demographics are much different from existing internet use…
But you can answer the questions, I assume?
What counts as a truck? Is a fire engine a truck, is a 4x4 (like a Landrover), a HGV (ie lorry), a box van?
What counts as a bus? Is a coach a bus, a minibus?
What counts as a bicycle? Is a pedal-and-pop (a pedal cycle with an engine)? The image shows part of a headset that might be on a bike, is that enough to call it a bike, might be a lightweight motorbike?
Is a hovercraft a boat? Is a helicopter an aeroplane (according to the people setting the question)? Do pedestrian facing lights count as traffic lights?
Then every now and again they add in an image that is, I assume, purposefully obscured (uniform noise) as if painted by an impressionist and titled "boring city with smog as viewed by someone with cataracts, there might be half a bicycle wheel in somewhere".
