[Quietcars] Quiet vehicle warning sounds

[Mark J. Cadigan]

There was little to no information about the implementation of this device 
in a technical since available. Lots of legal stuff, and laws, and reams of 
paperwork from the NHSTA, but only a press release or two from the auto 
manufactures.
