Self-Driving Cars May Soon Become Affordable


A new technology is popping up everywhere this year: solid-state lidar. With no moving parts, it promises to give self-driving cars sharper, better vision, at a fraction the cost of old-school, electromechanical systems. Older self-driving systems rely on "lidar' because without it, self-driving cars would be blind. Lidar consists of about a dozen lasers, shooting through telescope-grade optics, slinging around hundreds of times per minute, to generate 300,000 data points per second.
