Facebook AI: Billion-scale semi-supervised learning for state-of-the-art image and video classification

I wonder if Tesla could use a technique like this. Andrej Karpathy retweeted a Facebook AI tweet about this. Since at least February 2019, job postings for Tesla’s Autopilot division have said Tesla is looking for candidates who can:

Devise methods to use to enormous quantities of lightly labelled data in addition to a diverse set of richly labelled data.

In terms of weak labelling or light labelling, I hypothesize that driver action may be the source. For instance, if a driver goes straight through a traffic light, it is more likely to be green than red. If a driver goes straight without slowing down or changing the steering angle, it isore likely than not there is no obstacle obstructing the road.
