Science Questions

I have a suggestion for the noise that electric cars should be forced to make

I have a suggestion for the noise that electric cars should be forced to make:

A hissing sound like that of a snake, for three simple reasons:

(1) It is not a sound that you would hear in an urban environment so it will be unmistakable.

(2) Many animals are genetically predispositioned to avoid snakes as predators so they will avoid cars which may in turn reduce the amount of animal MVAs

(3) The noise is easily replicated with a broken whistle (a standard one with a metal barring inside of it)

Thanks for the good question, it got me thinking...
