It usually takes some time from the point "we have done all the basic research" to something that is successful in the market. Today, autonomous driving seems still to be in the basic research stage. If there was a research car, filled with ridiculously expensive hardware, able to perform at human level, I'd be more optimistic about the introduction of a marketable self driving car ten years from now. Take the mouse + graphical GUI example. It was demonstrated in the late 1960s but became only economically viable in the mid 1980s.
