This became obvious to me when during some period the regular crosswalks, stop lights, and buses got replaced by chimneys, trees, and mountains (!). It was right around the time when some big companies started advertising AI driven quadcopter services.
Ah, so that's what that's about. Here I was wondering why on earth a self-driving car would need help identifying a mountain (or need to identify one at all). "Surely they can't be that bad at avoiding obstacles," I thought.
