A recent survey by Nationwide Mutual Insurance Company found that a stunning 80 percent of cell phone owners talk while behind the wheel. That can be a big distraction, which some have equated with driving while intoxicated. And as the NHTSA reports, distracted drivers cause about 80 percent of all accidents in the U.S. That means hands-free cell phone use, while not perfect, is clearly the way to go.

As more and more states implement hands-free driving laws—California is the latest; with a new rule going into effect on July 1—having a headset for the car is vital. I'm a big fan of Bluetooth headsets, which leave no room for tangling wires or fiddly connectors when behind the wheel.
