writes "In his biography of the late Steve Jobs, Walter Isaacson explained that drunk drivers have been very good to those awaiting organ transplants (Jobs received a liver from a young man killed in a car crash). So, with the day of an autonomous Google car in every garage perhaps not as far off as one might think, Fortune's Erin Griffith asks a dark-but-necessary question: If driverless cars save lives, where will we get organs? Citing a 2013 study by the Eno Center for Transportation, Griffith estimates that if 90% of vehicles were autonomous, an estimated 4.2 million accidents would be prevented and 21,700 lives would be saved. And then, notes Makerbot CEO Bre Pettis, "we actually have a whole other problem on our hands of, 'Where do we get organs?' I don't think we'll actually be printing organs until we solve the self-driving car issue. The next problem will be organ replacement.""
