LG is showing off a prototype Bluetooth-enabled rearview mirror at 3GSM in Cannes. The idea is simple enough: pair up the mirror with your phone and get caller ID information displayed as you drive. In addition, the mirror functions as a hands-free speakerphone, so you don't have to dig around for your handset while swerving. Swerving should always be given your full attention, lest you miss a child and valuable points.
