Remember how airplanes used to have smoking and non-smoking rows? Well, if the FAA starts allowing people to use cellphones in flight, the airlines should set aside part of the cabin for those of us who’d prefer not to be subjected to some idiot yammering away on a cellphone during our next seven-hour flight to California. Amtrak has already designated cellphone-free “quiet cars” on many of its trains. It doesn’t always work, though, and the New York Times notes that the cars are self-policing, with many people ignoring the policy. They do so at their peril: at least one violator has had their cellphone smashed by a fellow commuter who was outraged to find someone talking in the quiet car.
