SPECIAL REPORT AUTONOMOUS VEHICLES: There are only a few dozen autonomous trucks on America's highways today, but the Commercial Vehicle Safety Alliance is already thinking about how to police them. They aren't above the law. It's up to people like our guest Will Schaefer, the Director of Safety Programs at CVSA, to figure out how trucking's safety rules can be applied to trucks that have no drivers. How will police officers pull over trucks that they can't communicate with directly? Can you charge a computer with causing, or not avoiding, a crash? Will Schaefer muses on how enforcement could proceed in the years to come.
