Some interesting points I grant you. But the truth of the matter is that although this tech MAY be ready in the near future there are too many variables that make integration as a full or nearly full replacement a fantasy. A few things to consider. The economy will crash IF we suddenly made this shift and then no one could afford all of these auto ran vehicle trips even if they do drop significantly in price ( which I highly doubt). People need vehicles for work and if trucks are the only vehicle using gas you can bet the cost of gas and trucks go up so then the work they do costs more and the entire cost of living increases but no one makes any money so…. Car enthusiasts won’t want to stop driving their fun cars. Laws would need to pass to allow for fully automated vehicles to hit the roads and not all jurisdictions will jump on board for that for at least a decade. If one person loses a life due to automated vehicles there will be an uproar. Assuming all these automated vehicles are accessible to the public, who actually owns them? If it’s a corporation, especially the maker of the vehicle you can bet the first death will cost millions. Until every vehicle can talk to each other and the infrastructure of a city this tech will not fully take over.
The most likely guess I have is a hybrid of these concepts to help improve driving. There MAY be some fully automated public accessed vehicles although I have my doubts. Electric vehicles have their place and will continue to eat into the marketplace and that’s about as far as I can see things really shifting for the foreseeable future. Trust in fully automated vehicles will take much longer and so it should. There may be a set of streets or even highways where you’ll be allowed to shift into full autonomous mode but it will take a long time before it is the norm. By the time that happens people and the economy may be in better shape to handle it.
