Earlier quoted context omitted.
Manufacturers of electric vehicles already are rolling out noise generators for low speeds, and it's likely those will become mandatory.
A friend's Renault Zoe EV has a 'whoosh' noise generator which thankfully can be disabled in the fusebox. To me it would be more sensible to only trigger a noise generator upon feedback from the parking sensors, instead of polluting the environment with constant sci-fi noises.
