I'm sure at least the collision avoidance part of the system would need to poll at a much higher rate than 15fps. That's up to 67ms latency you're adding. With enough miles that delay could kill people.
If they're actually feeding data at 15 FPS into their ML model, then what the fuck were they expecting? Correlating movements at those framerates would be nigh-impossible.
Relying on ML for this is already comically irresponsible, but that'd just be ridiculous.
Where does this figure come from?
Human eyes are almost comparable in terms of a framerate based on the neuron spiking rates, which are somewhere over 250-500Hz max. Obviously that's not directly comparable though, but it gives an idea of how well we can deal with moving objects.
