A single fixed sound?
A single universal fixed sound is probably missing a trick. If we mandate that every EV sounds the same as every other EV how will we be able to tell if the best warning sound was selected in the first place? If there are a range of sounds in use then time will tell which are effective and which are not, just as time has done with various emergency vehicle warning sounds. There needs to be just enough commonality so that a warning sound is recognisable for what it is, but no more than that - for the time being.
