Elon Musk calls him "batshit crazy," but Dan O'Dowd has built software for the F-35 fighter jet, the B2 bomber, and to secure U.S. nuclear forces. He's also built a microprocessor for Mars, worked on the Mac at Steve Jobs' request, and completed a ton of test drives of Tesla full self driving. His conclusion: it's worse than a drunk driver. And: it does not recognize small children. In this TechFirst we chat with Dan about his tests, what he thinks is wrong with Tesla, and why Tesla is falling behind General Motors and Google (Waymo) in full self driving.
