How self-driving cars will make our cities more charming

Everyone's trying to get ready for roads that will be filled with more and more self-driving cars. But just as the first cars were imagined to be like horse-drawn carriages without the horses, it's easy to fall into the trap of thinking that a future with self-driving cars won't be that different -- except that we won't have to drive. As a scientist who specializes in imagination and human behavior, it's interesting to me to try to figure out how technology will change our world. It can be challenging to predict how things will change. But one thing that is important to think about is that self-driving vehicles will be able to go places without anybody in them.
