How would the road network change, after all cars are self-driving?
In a future where all cars and public services are self-driving the way, I am assuming traffic congestion would be seriously limited, if not removed completely, because the road network would also have a companion communication network between vehicles, allowing the implementation of some optimal bandwidth occupation algorithm.
Besides the technology that will need to be installed along the road, how do you imagine the road network to be affected by that? (for instance: less multi-lane roads, or more single lane roads, with no traffic signals? or with different ones? what about parking; there are just examples, please don't refrain from adding your thoughts).
