Self-driving cars and the ethics of AI

Personal transportation in a world void of human drivers will presumably be much safer, right? That's great, but it also means that a lot of people are going to be without jobs. Insurance companies won't need nearly as many claims adjusters, the DMV won't need to be nearly as large as it is today, police forces could be greatly reduced and as morbid as it sounds, hospitals won't need as many doctors (in 2012, motor vehicle collisions sent nearly 7,000 Americans to the ER each day). With fewer people dying in auto accidents, there won't be nearly as many organ donations, meaning that some sick people who might have survived thanks to a transplant won't live as long. It's a seemingly endless chain reaction of cause and effect.
