Porcelain Privacy

That when you step into the bathroom your phone, house or cell or even VOIP/Vonage, rings off the hook. It happens persistently, leading you to believe that the new electronics in the home - your computer, flatscreen TV, air conditioner, electric toothbrush - all have tiny pinhole cameras in them that have effectively turned your life into the Toilet Truman Show. Remember to wash your hands.

Airbag Alarmist

While reaching across the front seat to place your briefcase or other object on the passenger seat, be aware that your cell phone, metal belt buckle, eye glasses or pacemaker could send a signal to the airbag and cause it to inflate. This would cause horrific damage to your ribs and probably kill you.

It's also a danger to have a passenger put their feet on the dash, as the airbag might go off for no reason and instantly snap them in two at the waist and propel them into the back seat.
