People using cellphones while driving has become an enormous problem, so laws restricting phone use keep getting tougher. This device provides a way to block unsafe phone use in a car, while still allowing authorized methods of communication.
It seems like a no-brainer. Using handheld personal electronics while driving a car simply isn't compatible. So now the NTSB is asking all states to introduce strict laws to limit their use.
This can't be good. If texting and using your GPS doesn't have you sufficiently distracted while you're supposed to be driving, perhaps this Bluetooth equipped rear view mirror will do the trick.
Distracted driving is a serious problem, so lots of people are coming up with ways to stop you from using your phone while driving. The latest is Drive First for Sprint Android phones, which senses when the car is moving and locks down most of phone's functions.
