There are many reasons the self-driving tech industry has suddenly found itself in this “trough of disillusionment,” and chief among them is the technology. We don’t yet know how to pull off a computer driver that can perform as well or better than a human under all conditions.
It turns out that the human ability to build mental models isn’t something that current AI can just learn, no matter how much data it’s fed. And even once we have the technology, we’ll still have to deal with all those unpredictable humans in cars, on bikes and scooters, and on foot. The more self-driving vehicles hit the road, the more pressing the safety concerns and legal and regulatory issues will become.
