What it is: Car Widget is a scrollable list of extra-large icons, providing easier access to the apps, contacts and shortcuts you use most while driving.
Why it’s a good widget: The jumbo icons will help you keep your eyes on the road. I recommend adding the ICS Voice Search Shortcut and the Screen Timeout Toggle (both mentioned later in this slideshow), as well as a “Navigate Home” shortcut (as detailed in last year’s list of widgets). A $2 “Pro” version can detect when you’re in the car, and toggle certain settings such as Bluetooth and GPS.
