In the US, self-driving and autonomous vehicles are something that is being worked on in the military and private sectors. Google is one of the largest firms working in the autonomous vehicle market, but many automakers are working on the tech as well. We are still likely several years away from autonomous vehicles on the roads in the US.
In the Netherlands, a trucking company is pushing hard for self-driving trucks to cruise the streets between Rotterdam and other Dutch cities. Rotterdam is the largest shipping port in Europe. The trucking firm wants these self-driving trucks to be cruising the streets in the next five years.
Currently traffic laws in the Netherlands are being reviewed to make large scale testing of self-driving vehicle tech on public roads possible. Testing would start on computer simulations and then move to closed track testing before being allowed on public roads.
