Autonomous Vehicles from Darpa

Government can do good. I talk a lot about autonomous home delivery vehicles, and also electrical tethering of autonomous cargo wagons.
Re-purposing our asphalt, rubber and microprocessor. Fixed speed diesel electric tractors tethering 10 to 20 wagons. Wagons moving autonomously around the large FedEx parking lots, re-organizing themselves.

Autonomous home delivery, how cheap, efficient.

Allowing safer roads, seeking triple the energy efficiency, and making life so much more convenient for us all.
