Well actually it won't transform your car, but Android Auto can completely integrate your Android device with your vehicle, and let you control everything you need to have at hand: navigation, reminders, address book, and sound control.
This technology is supported by main car brands in the market. There are about thirty different brands that already let you enjoy the benefits of Android Auto.
Android Auto is a pretty useful application. It doesn't transform your car into a futuristic vehicle, but it's a pretty cool copilot.
