The single system you're describing, with all of its complexity, is a subset of what is required for autonomous vehicles. We will continue to have road construction, tunnels, and weather long past the last human driver. Improving the system here simply improves the system here -- you cannot forsake this work by saying "oh the autonomous system will solve it" -- this is part of the autonomous system.
