Self-driving cars are moving from science fiction to showroom fact, or at least to a car summoning platform. Waymo, the self-driving car division of Google, has ordered 82,000 self-driving cars for delivery through 2020. Cruise Automation, from General Motors, is perfecting their own fleet. Countless companies are driving full-throttle into the future.

In April 2018, after it became known that Google was collaborating with the US Department of Defense on Project Maven, over 3,000 employees signed an internal memo asking CEO Sundar Pichai to (a) cancel the project immediately, and (b) enforce a policy stating that the company would never build warfare technology.
