A few million self driving cars and trucks should be on the road by 2022. Afterwards a few million per year will be added with self driving car conversion kits and new cars and trucks.
Tesla Motors and other companies will deploy millions of self driving cars.
This can lower the cost of car per trip mile by 5 times.
Self driving Uber, Lyft and other shared vehicles would be able to service the same number of riders with fewer vehicles.
The transformation to self driving will be more rapid than many forecast. Many forecast it will take until 2050 for the full impact to be felt.
Amazon is looking to revamp the global supply chain by reducing layers and getting much more efficiency in shipping, drone delivery and self driving vehicles.
Enabling Trade: Valuing Growth Opportunities finds that if all countries reduce supply chain barriers halfway to global best practice, global GDP could increase by 4.7% and world trade by 14.5%, far outweighing the benefits from the elimination of all import tariffs. In comparison, completely eliminating tariffs could increase global GDP by 0.7% and world trade by 10.1%. Even a less ambitious set of reforms that moves countries halfway to regional best practice could increase global GDP by 2.6% and world trade by 9.4%.
The World Economic Forum boost in global GDP was only from getting to half way the global best in 2013. The supply chain can be radically improved with self driving cars, trucks and drones.
Amazon already has super efficiency robotic warehouses.
Cargo Drone Motherships and drone swarm delivery
Single item delivery will not where the supply chain transformation ends.
Having cargo drone motherships that send drone delivery swarms will be more efficient. The small drones that make the end point delivery would not even need to be able to fly back to the drone mothership. They could be picked up by self driving trucks and cars.
Deliveries could be ordered online and delivered within 30 minutes. This would drastically reduce office and retail storage and inventory.
Lowering supply chain barriers is effective because it eliminates resource waste and reduces costs to trading firms and, by extension, lowers prices to consumers and businesses. Supply chain barriers can result from inefficient customs and administrative procedures, complex regulation and weaknesses in infrastructure services, among many others
This first stage of the robotic supply chain could boost Global GDP by 25-50%.
The second act in the 2030s would be transformation of cities to leverage the hyper-efficiencies of the robotic supply chain.
