Ok, a wind blows a empty paper bag on the road. A human will see by the way it moved that it is empty and safe to drive over. What will AI see? A driveable road or a road with a rock on it?
I still think that without the "model of the world" no AI will be capable of driving. And that model requires GAI.
Interestingly, I remember this exact scenario was a noted problem for some sort of computer-controlled shock absorbers that I saw on the "Beyond 2000" TV show in the mid-90s. In many scenarios, the shock absorbers could detect bumps and holes in the road and compensate perfectly, resulting in a ride that was smooth as glass.
But they still hadn't figured out how to differentiate between a crumpled paper bag and a rock, or a pothole filled with water vs a smooth surface. Otherwise, it was really impressive.
I feel like Level 4 or 5 Autonomous Driving will be the same -- there are just some problems that will never be solved well enough to make it work acceptably.
I think the vehicle should alert the driver, and being controlled slowdown until it is overridden. Sorry, driver, you are inconvenienced. Maybe you are in the carpool / AI-only lane, so it's not a big deal. Yes, there probably should be an AI-only lane for now.
This could exist now, but we have set sights on Level 5 at the expense of pragmatism.
