There is currently no autonomous car to buy anywhere. No taxi, truck, bus driver has been replaced so far and no one knows when it will happen and if it will happen at all.
I think you're deluding yourself. The people working on the problem of automated driving (just as one example) aren't going to stop. The technology that enables it; the sensors and algorithms aren't going to cease to be developed. They're going to succeed and whether that's a year from now or ten years from now, it doesn't really matter. And I think the same holds true for the most important technology - some form of AI. It would appear to me that the largest questions of how to develop (even an imperfect, less-than-human-capable) intelligence have been resolved. The only thing remaining is the refinement and distribution of the final product.
Once that takes place, I don't think there will be any stopping the technological, scientific, economic and societal upheaval.
