Since we’re wandering into the OT weeds…
Ah an article that’s padding around an embedded video. Joyous. For once I have the luxury to burn ~15 minutes on < 5 minutes of written material.
This effect is the strange interlude of PWM (Pulse Width Modulation) brightness control popular for LEDs and the mechanics of a digital image sensor’s rolling shutter. Cheap LED Christmas lights do this by rectifying the AC voltage - unfiltered - and thanks to the fast response time of LEDs relative to incandescent, this is perceived as 120Hz flicker which is rather annoying.
The automakers love PWM controllers because they’re slightly cheaper than providing LED controllers capable of multiple currents and also capable of an arbitrary number of output levels. A better solution would be to take advantage of the near-instantaneous response time of LEDs and up the base frequency by an order of magnitude; as an added bonus this would do away with the distraction of panning your eyes across tail lights and seeing a line of dots (ala cheap LED Christmas lights) whenever you scan your human eyes across a scene when behind the wheel.
Presumably a well-conceived autonomous driving AI would treat brake lights and turn signals the same way that the analog human mind does - as a signal of intent rather than a solid tell of action. Like for a a human, a driving AI should treat a signals as a trigger for additional scrutiny of the vehicle’s future behavior.
Of tangential interest, at ~1:15 the video shows was looks to be a simulation of LIDAR, which won’t care about visible light and produces short-to-intermediate distance geometric data for the driving AI to work with.
