Turning one system off in favor of another is basically admitting that they have no faith in their software. Also isn't driving a car with sensors (without self-driving tech) basically a giant data collector? The mere act of driving a car (with a human brain) should help a SDV system understand a false-positive and a false negative simply by learning what a human does in contrast to what the machine thinks it is supposed to do.

I imagine this is what separates Waymo and the others. I feel like Waymo is using math/neural nets, etc.. whereas Tesla and Uber were probably giant hand-written if/else machines. I have nothing to back that up, except that that's kinda what this article is about.
