No teenager, or adult for that matter will willingly opt for a car key that prevents their cell phone from working.  Utah University thinks otherwise, though.  They’ve invented a car key that communicates with your cell phone.  When the key is extended from the device, it emits a signal to your celly rendering it useless.  They’re calling it Key2SafeDribving and apparently a private company has licensed the tech.

So what happens if you get in an accident and can only reach your phone?
