It is phenomenally simpler to have autonomous driving in an area where the only things on the road are autonomous and there is a standard for interacting cross manufacturer. Many new cars, and in some countries all new cars (by law), have enough sensors to be made self driving. Standards are already being worked on. A basic level of autonomy - good enough for an area without human drivers - is being worked on by ever…
The only way I see self driving cars dealing with all this in the near future is if the roads were totally fenced off from everything else so that only self driving cars were on them more like trains. However, this seems like such a big infrastructure investment (and just a big change overall) that I just don't see it happening within the next few years.
Our cities (at least in America) can't even put in bike lanes, or provide reliable trains, which is a 200 year old technology, so how are we to expect them to completely overhaul our infrastructure to help a technology that barely even exists?
