Scientific American has an article by Sarah Simpson, with a new worry about hybrid cars. You may not have begun to worry about this one yet. The question is, are hybrid cars too quiet to be safe for pedestrians? The article takes a "wait and see" posture. If you were reading my blog four years ago, you know that for me, car engines became dangerously quiet 56 years ago. With my passion for biking through intersections by relying on sound alone to tell me if they were empty, I was lucky to survive the quieter engines that Detroit turned out in 1952.
I'm over the hump on this issue. Bring on the quieter cars, and - maybe - quieter towns and cities as well.
