Jim Keller's viewpoint is essentially, largely, correct.  The challenge of autonomous driving is primarily a computational problem, a data problem.  As far as human behavior is concerned, the ongoing advent of autonomy will gradually remove that human variable from the circumstance.  Plus human behavior itself is, foundationally, indeed a matter of patterns and habits.  Humans will make mistakes, and occasionally will intentionally make a "bad" decision out of curiosity or even via nefariousness, hence humans are not (always) "trustworthy."  But even those intentional "bad" decisions are arguably matters of connecting the dots involving, even with them, degrees of predictability.  If we could just find all the dots, or all the pertinent dots, we'd therefore know what's coming over the horizon and not be surprised.  As for the "craftsman" variable of human behavior, I also agree that "craftsmanship" and even of "art" or "aesthetics" is involved with everything that humans do.  John Dewey's "Art as Experience" (and also Spinoza), is my reference for that position.  Every experience, or every completed experience, as Dewey might say, involves a degree of satisfaction or of completion, including an epistemological component (learning by doing, or learning through experience).  And so even the ditch digger, or the assembly line worker, or the baseball player, or the chef, or the historian, or the mathematician, or the novelist, can (and does) develop a sense of "being good" at their task, at whatever it is that they're doing, and so even a brick layer can be involved with amazing craftsmanship and aesthetics, and the ballerina's training infuses all that she does, and so on and so on.  Human beings can very much be reduced to "ballistics problems," it's just that we may not have all the internal "dots" to no longer be surprised by their full range of possible actions.  But then again, just how many "dots" are needed to be able to develop an autonomous driving vehicle that is exponentially safer than average human drivers?  Or even safer than expert or professional drivers?  To have autonomous vehicles that meet the basic concerns of the regulators?  Eventually those few "dots" that still surprise will become fewer and fewer, until they are possibly even removed from the landscape altogether (or perhaps removed from the computer's computational "awareness" although perhaps still limited by the capabilities of the vehicle itself to be able to respond appropriately in whatever time might be available for an effective response).  In decades hence, it's very likely that the only persons driving their own vehicles will be the antique hobbyists or law enforcement or military (whether the Good Guys or the Bad Guys), or rogue pirates (e.g., Firefly) on some other planet.
