I think we can make more progress by lobbying for an appropriate sound rather than trying to fight it altogether.
Personally, I'd like EVS to be as quiet as possible. I can envision a future where an intersection will be the quietest point on the road - no engines drumming, no tire noise, just a slight whrr when the light turns green. Contrast that to what it is now, with loud exhausts and heavy vehicles trying to accelerate. Not peaceful, huh?> Now imagine the same intersection with EVs equipped with noisemakers. If they sound anything like backup alerts on trucks, it doesn't take much to hear the cacophony of racket. Probably worse than the ICE noise we have now. So, I will by proposing something which could turn into a national automotive vehicle alert requirement: 1. unique from other road noises (so the blind can recognize it), 2. no louder than necessary to hear from 5' away and < 30db. 3. nonaggravating to hear; for example a softly pulsing pink noise.

Because there are groups with an agenda, who stretch whatever circumstances come along to support their cause, whether the fact justify it or not. :-/ -- The storage battery is one of those peculiar things which appeals to the imagination, and no more perfect thing could be desired by stock swindlers than that very selfsame thing.
