Fully autonomous vehicles? Programmed to be safe, not to crash into me? Hey! I can ignore it. Drive or walk the street in front of it, regardless of traffic lights. Deliberately stand in front at an intersection, preventing it from moving forward. Hold a mirror in front of its video or laser sensors - that ought to confuse it. What a wonderful source for entertainment, tricks, and trouble making. Yup, autonomous vehicles.
