Here in the US we're already seeing driver to road controls from a system that does lane searching and will slow down the speed of the truck with it's sonar. These trucks suck to drive in the winter and are dangerous on ice. Driverless cars sound like a great idea, but IMO it's just like the drones. Look how many states oppose them and the reasons as well. I'm sure in 100 years the driverless cars are definitely possible. I was sitting in a semi on Saturday with a load of corn wondering what the ag industry will do if the train lines keep getting restructured and removed? What new means will they move mass amounts of freight? It's crazy how far south the trains have went. I have no answers for this topic, but I fear my children and their children will see it.
