Engadget on the latest creepy / comical hack for bluetooth hands-free wireless. "The Car Whisperer waits,... sending out pings for hands-free devices. When one comes into range, it tries to negotiate a connection wherein Car Whisperer will pass it the predicted passkey, and allow the attacker to listen in on conversations in the car (but not calls), or inject audio into the line."

Just what Audio should one "inject" into a vehicle moving at 60 mph?
