Recently on my drive home, I noticed one of those odd-looking, self-driving taxis from Waymo. After a brief fixation on the technology—360 cameras, sensors and lasers—mounted to the car’s exterior, I turned to look inside. Not seeing anyone in the driver or passenger seats was as interesting as it was unnerving. “Welcome to the future,” I said to myself, “the concept of self-driving vehicles has finally arrived.”
