>and completely silent As is a properly cared-for bicycle, although a human-powered bicycle isn't usually going very quickly. Whenever someone brings up e-vehicles and their silence, I suggest that they should all make some sort of nominal noise indicating speed. For centuries, we heard wooden wagon wheels creaking and/or hooves clop-clopping on the road. It's time to bring that back, and insure that the pace matches the speed of the vehicle so that pedestrians, even the blind, can intuit speed and direction of travel. (n.b. we'll have to get rid of loud sound systems in cars that can be heard for blocks - pity.)
