Continental, the big European auto parts company, has a practical solid state LIDAR.[1] It's the Advanced Scientific Concepts flash LIDAR technology, which works well but cost too much when ASC was making it by hand in Santa Barbara, CA. What they don't have is a car company ready to buy enough units to make volume production worthwhile. In the meantime, they're selling a few units to commercial drone operators.[2]
