Google's Robo-Cars Hit 2M Miles, Confirm Driving Is Dadgum Tricky

I can't tell from the back seat who's in control of Google's autonomous Lexus. The SUV is prowling the streets of Mountain View, California, but it's only after lead engineer Dmitri Dolgov flings his hands into the air that I realize he may be in the driver's seat, but the computer is in control. After a flurry of pronouncements from companies racing headlong into autonomous driving, Google's venerable project feels like an afterthought. After all, Ford CEO Mark Fields promises hundreds or thousands of autonomous taxis by 2021. Lyft co-founder John Zimmer says most customers will tool around in robo-cars within five years.
