It's an interesting thought, but I don't think this will be a significant problem. The inevitable combination of laws, surveillance, and social norms will, as it does now, keep the vast majority of people from doing random asshole acts like this. The self-driving trucks will, by definition, be equipped with omnidirectional, high resolution 3d cameras. Who was that guy who kept cutting off our truck? Well, we could 3d print his face and license plate if you'd like. Also, the trucking industry will run to lawmakers the very first time this happens, and they are a very strong lobby. Finally, it's just a shitty thing to do, and everyone will understand that. Much like shining a laser at a plane is almost universally reviled, there will be social consequences for being that guy who torments driverless trucks. By the way, "robotic carts that move supplies to workstations"? Is this a common thing? Can you say where you work?
