This article takes a deep dive into lidar technology. It explains how the technology works and the challenges technologists face as they try to build lidar sensors that meet the demanding requirements for commercial self-driving cars.
The bottom line is that while bringing lidar costs down will take a significant amount of difficult engineering work, there don't seem to be any fundamental barriers to bringing the cost of high-quality lidar down below $1,000—and eventually below $100. That means the technology—and ultimately, self-driving vehicles that depend on lidar—should be well within reach for ordinary consumers.
