Once they were the stuff of science fiction, but almost out of nowhere, self-driving cars have become a reality. Experts suggest that driverless cars will appear on our roads within five to twenty years, and Uber has already piloted a self-driving car program in select cities.

This fascinating and timely volume offers a diverse array of perspectives written by experts on this twenty-first-century subject.
