With driverless cars on the horizon there is renewed interest in a classic ethical dilemma, the trolley problem. What decision would you make?
You spot a trolley barreling down the track towards five workers. There is a lever you can pull to switch the trolley over to another track, but there is a worker on this track as well. You quickly assess and other than the lever, there are no other feasible options. It is either one life or five lives. Do you pull the lever?
