I’ve read a few emails and I’ve changed my mind. Ban car porn (by which I mean human porn in cars not, say, films about AMC Pacers and El Caminos gettin’ it on). I was taking the position that your car is an extension of your home, but it’s really not. One: You can make a perfectly legit safety argument (porn is designed to be distracting unlike, say, Diane Rehm). Two: it is very easy to expose kids to it. Three: It’s creepy. In short, the infringement is clearly minimal while the potential damage is considerable. If you must watch porn in your car, do it in your garage.
