In addition to founding Udacity, Thrun is also the CEO of Kitty Hawk, which earlier this year showed off its entry into the "flying car" race, the Flyer. Of course, as many people pointed out, the Flyer is not a flying car. Not even close. Instead, it's like a jet ski that you can ride above water, or a "flying motorcycle," as Thrun elaborated on Tuesday. He expects the Flyer to be ready in February, and he called riding it the "funnest" experience of his life. "I've flown it and I'm still alive," he joked.
