TED-Ed: Sajan Saini: How do self-driving cars

It's late, pitch dark and a self-driving car winds down a narrow country road. Suddenly, three hazards appear at the same time. With no human at the wheel, the car uses smart eyes, sensors that'll resolve these details all in a split-second. How is this possible? Sajan Saini explains how LIDAR and integrated photonics technology make self-driving cars a reality. [Directed by Artrake Studio, narrated by Addison Anderson].
