I am very skeptical that there will ever be a ‘driverless truck’.
First, I am familiar with the technologies used by Google in their driverless car pilot program. Not only is it expensive, and ill suited for rain/sleet/snow...but the computing power necessary is huge.
And somebody has to maneuver the truck at the dock, at weigh scales....fuel it up on long hauls...tarp it, put chains on the tires...put out warning markers if it breaks down.
I honestly don’t see this happening anytime soon.
I don’t think I’d feel safer passing a driverless truck on the road, that’s for sure.
You lack imagination.
