> Trucks can drive themselves. Companies like IKEA are already doing trials, and when they have the data that proves how much money/liability/time they're saving, it won't be long before they are adopted as the norm company-wide.

I agree. When this is cheaper than using a human driver, it will be amazing how quickly it will be adopted. I have always thought that long haul trucking and loading dock to loading dock trucking (like IKEA is doing) will be the first widely adopted driverless transportation. Limiting the vehicles to a selected set of roads where there is little cross traffic and few pedestrians makes the task much easier.
