How the Self-Driving Dream Might Become a Nightmare

What will happen if we just accept that a certain number of pedestrian deaths are an inevitable part of adopting autonomous vehicles?

I’m enthusiastic about the potential for autonomous vehicles. Their great promise is that they could be safer than fallible human drivers, who kill 37,000 Americans a year. And I do believe AVs will be safer. They will not drive drunk or distracted, and they will not get overwhelmed by more information to process.

How much safer they are, though, will depend on the humans who design them and make the rules. Their driving style, whether aggressive or timid, is something that will be baked into their programming, based on real-world traffic environments and how traffic laws are enforced. The question is the same as always: Are we programming for a world that’s built for humans, or a world that’s built for cars?
