FSD - why 36Hz?

As we all wait for the next big FSD release to v13, and after looking at the specs of how this works using HW4, why are the cameras capturing image frames at 36Hz?

Anyone here have any info on that? Does this have to do with constraints of processing or does it have something to do with the flicker of LED lights or something? I know in photography/videography, certain shutter speeds or frame rates cause banding or other image degradation under LED lighting situations. Seems a lot of vehicles and stoplights and whatnot these days are LED.

At 36Hz and traveling 80 MPH on the highway, the image updates every 3.25 feet. Is that ‘enough’?
