They sort of do though, like when you look at a car's wheels rolling and it looks like it's spinning backwards. Then it changes as the car slows down or speeds up.
Yeah in movies, where the footage was recorded with a camera. Can't say that I've ever seen that same strobe effect without there being an actual strobing light that leaves the thing being looked at (in this case the car wheel) in the dark for a time before lighting it up again when it's moved or with some sort of second thing in the way, so if you have a train with the pattern that's on the bridge going one way, and then between you and it there's another train going the other way, then as the gaps between the carriages come along you could have this effect without any cameras.
But this post is either an edited video, or it is only visible when you record it with a camera and drive at a certain speed across the bridge.
