New from Ford: Drivable iPods

Ford's new MyTouch software makes cars act like smartphones.

The latest version of the Microsoft-based software turns the car's entertainment system into something much more like a rolling smartphone able to connect to other devices and even run downloadable applications from outside companies.

Ford engineers have a lot more to contend with than cellphone makers do. You wouldn't want to leave your iPhone inside a parked car on a scorching hot day so how will delicate electronics embeded in your car react?

Besides that, distraction is a much bigger issue when you're driving a car than when you're walking down the street.
