Self-driving vehicles could be coming to an airport near you

The Auto-DollyTug — which has a safety driver on board — can autonomously pick up a container and transport it directly to the aircraft. It can go backward, forward and sideways, or rotate 360 degrees on the spot, a handy feature in congested airports where other vehicles are transporting fuel, water, catering and people.
