Microsoft has a home in the automotive world, but it doesn't have a way to bring a phone's interface to your car's infotainment system -- there's no Windows Phone equivalent to Apple's CarPlay. That might change before long, though. The software giant used a presentation at this week's Build conference to show off Windows in the Car, a conceptual platform that would adapt Windows Phone's apps and basic functions to in-vehicle interfaces. Not surprisingly, the MirrorLink-based tech looks like a cross between Microsoft's mobile and desktop interfaces; while you're running mobile apps, they get more on-screen buttons than usual to help you complete tasks faster and keep your eyes on the road. The software also focuses more on voice commands (Cortana is mentioned as a good fit), and it could eventually restrict complex app functions while you're driving. You might not get to add music to a playlist until you're parked, for instance.
