Would you buy a car programmed to kill you for the greater good?

Should a self-driving car kill its passengers for the greater good – for instance, by swerving into a wall to avoid hitting a large number of pedestrians? Surveys of nearly 2,000 US residents revealed that, while we strongly agree that autonomous vehicles should strive to save as many lives as possible, we are not willing to buy such a car for ourselves, preferring instead one that tries to preserve the lives of its passengers at all costs. Driving our own cars might be a enjoyable pursuit, but it's also responsible for a tremendous amount of misery: it locks out the elderly and physically challenged and is the primary cause of death, worldwide, for people aged 15 to 29. Every year, over 30,000 traffic-related deaths and millions of injuries, costing close to a trillion dollars, take place in the US alone (worldwide, the numbers approach 1.25 million fatalities and 20 to 50 million injuries a year). And, according to numerous studies, human error has been responsible for at least a staggering 90 percent or more of these accidents.
