What? Have you never looked at another car's wheel on the highway? Or is that something that only occurs to some people (doubt it).
Eye vibrations can cause the effect to be visible to the naked eye. If even humming can do it, the road vibrations might too.
I'm confused. I thought seeing/measuring lower frequencies due to a low sampling frequency, where the lower perceived frequency is basically the modulus of the real frequency and the sampling rate, is a well-known phenomenon independent of the actual sensor implementation.
I guess it is, but it's unclear why it happens outside of recordings.
