True Level 5 driverless cars that are fully autonomous and work in arbitrary environments, even in just the US, is just not happening any time in the next 30+ years if you ask me. Smaller more gimicky stuff in limited environments already exists though. And the level 2 stuff out there is awesome and a major value-add. The technology that has been put out so far is amazing and the engineers behind it should be very proud of that work. But there are too many "but if..."s for driverless to be mainstream just yet. We need a system that can really think like a person can. Something that has very high-level abstractions and understands context, situational state and human behavior. It's not a problem that can be just solved by slapping more and higher-resolutions sensor packages onto the car, though that will absolutely be necessary. (And until that becomes MUCH cheaper, that's a major roadblock as well)
