"Patrick Lin, philosophy professor at Cal Poly, San Luis Obispo, is one of the few philosophers who’s examining the ethics of self-driving cars outside the Trolley Problem. There are concerns about advertising (could cars be programed to drive past certain shops shops?), liability (who is responsible if the car is programmed to put someone at risk?), social issues (drinking could increase once drunk driving isn’t a concern), and privacy (“an autonomous car is basically big brother on wheels,” Lin said.) There may even be negative consequences of otherwise positive results: If autonomous cars increase road safety and fewer people die on the road, will this lead to fewer organ transplants?"
