A common fantasy for transportation enthusiasts and technology optimists is for self-driving cars and trucks to form the basis of a safe, streamlined, almost choreographed dance. In this dream, every vehicle – and cyclist and pedestrian – proceeds unimpeded on any route, as the rest of the traffic skillfully avoids collisions and even eliminates stop-and-go traffic.
Today, autonomous cars are becoming more common, but safety is still a question. More than 30,000 people die on U.S. roads every year – nearly 100 a day. That’s despite the best efforts of government regulators, car manufacturers and human drivers alike. Early statistics from autonomous driving suggest that widespread automation could drive the death toll down significantly.
There’s a key problem, though: Computers like rules – solid, hard-and-fast instructions to follow. How should we program them to handle difficult situations?
