Apple's 2012 Worldwide Developer's Conference keynote has already taken place, and perhaps one of the things that caught our eyes aside from the new MacBooks and iOS 6 is the inclusion of Siri into our cars.

Called Eyes Free, it's basically just a steering wheel-mounted button that will activate Siri on the iPhone or iPad. Eyes Free will let you talk to Siri through the car, and gives you access to a wealth of information without using both your eyes and hands.

Apple reports that BMW, General Motors, Mercedes-Benz, Land Rover, Jaguar, Audi, Toyota, Chrysler and Honda are all signed up to start offering Eyes Free within the next 12 months.
