Apple is working with car manufacturers to integrate Siri into select voice control systems. Through the voice command button on your steering wheel, you’ll be able to ask Siri questions without taking your eyes off the road. To minimize distractions even more, your iOS device’s screen won’t light up. With the Eyes Free feature, ask Siri to call people, select and play music, hear and compose text messages, use Maps and get directions, read your notifications, find calendar information, add reminders and more. It’s just another way Siri helps you get things done, even when you’re behind the wheel.
Recently, developer Steven Troughton-Smith posted a video of the upcoming 'iOS in the Car' feature in action. iOS in the Car will bring an even deeper integration with car multimedia systems. More information on that can be found here.
