> I just wonder if self-driving is one of those problems where you can get 95% of it solved, but the remaining 5% remains uncrackable. It's felt that way to me from the start. I tend to dwell on small details more than necessary and more than I imagine most people do. When I take a drive it's not just a drive to me, it's a series of countless decisions with more ambiguity than I'd trust to an algorithm. "Clean" driving conditions have to be seen as the edge case, not the norm. I believe the AI that gives us acceptable search results is so far removed from the kind of human cognition that understands the world and reliably resolves everyday ambiguity that we're not only not close, we haven't even started on a track that gets us there.
