We can do all kinds of things with cars, these days. Electric vehicles seem to be almost silent, the only noise the sound of tires going over uneven surfaces. Wonderful, indeed, and in direct opposition to the machine-gun exhausts of passing Harleys.
But here's something we haven't yet worked out: the astoundingly loud noise of the slamming of cars doors. Yes, especially by neighbors at 2 am. It would be easy, very easy, to install a feature on any car that closes the doors quietly. The Honda mini vans have it already. Dammit, even my kitchen drawers have little things that close them quietly for the last two inches. Why not the midnight car riders?
Stress comes in many forms. Noise pollution is one. We don't need this.
