The automotive AIs are narrow pseudo-spatial models that are good at extracting spatial features from the environment to feed fairly simple non-spatial models. They don't really reason spatially in the same sense that an animal does. A tremendous amount of human cognitive effort goes into updating the maps that these systems rely on.
What you're describing is what's known as an "end to end" model that takes in image pixels and outputs steering and throttle commands. What happens in an AV is that a bunch of ML models produce input for software written by human engineers, and so the output doesn't come from an entirely ML system, it's a mix of engineered and trained components for various identifiable tasks (perception, planning, prediction, controls).
Help me understand - my mental model of how auto AI work is that they're using neural nets to process visual information and output a decision on where to move in relation to objects in the world around them. Yes they are moving in a constrained 2D space but is that not fundamentally what animals do?
