Homebrew self-driving tech gets millions in backing

Those with long memories will know Hotz from his days as Geohot, the hacker that cracked the iPhone and PlayStation 3. The engineer has founded a company, Comma, on the principle that cheap sensors and machine learning makes it possible to make a system for a few thousand bucks. It's a claim that Tesla was quick to trash, saying that while it's easy to build a system for a "known stretch of road," a real self-driving car is a much harder proposition. Still, if the folks at Horowitz are opening their bank accounts, even slightly, then they must feel differently.
