When you live someplace like I do, where there are a lot of blind corners, no noise is a dangerous thing. I think the manufacturers ought to install something that makes *some* noise--less than regular cars make now, but just enough to alert pedestrians and even animals.

How about something pedestrians could wear/hold that would alert them to an approaching vehicle? Perhaps embedded electronics in clothing or accessories.
