It really does feel like an "emperor has no clothes" situation. Companies are spending billions of dollars and articles are being published daily about a technology that hasn't remotely even shown to be feasible. Sure, they've figured out how get a car to do highway driving and that's making some long distance commuters very happy. But the stuff they're talking about, like replacing Uber drivers with a computer... there's no reason to think that's even possible with our current level of technology. Moving from highway driving to city driving at least an order of magnitude more difficult to do. Building a car that can detect lane markers does not mean you're going to be able to figure out how to detect jaywalkers or interpret road cones. An effective driver needs to be able to look several cars ahead in order to navigate complicated traffic situations and there's no indication that anyone has come close to technology required do this.
What's really disappointing is that the tech community, like those of us on Slashdot, really should know better. For a website that so often displays Luddite tendencies, it's strange that so few are willing to point out that autonomous cars just aren't going to happen.
