Yes, a few people will die. More than a few. But I would bet anything that even in the short-term, and especially in the long-term, far fewer will die than if there were human drivers in those cars.
Over a million people a year die from traffic related incidents. It's arguably the most dangerous things many people do aside from poor diets and smoking. We need to bring this number down, and quickly. It's not going to happen as long as humans are driving.
