Electric cars have to make noise on purpose because otherwise it would be a silent car. And most of these noises are are weird futuristic WEEEE-00000 UFO sounds. Therefore I posit that we should be able to change the noises our electric cars make
EDIT: These suggestions are Top-Notch! Keep em coming!
They’re the same for safety. People need to build a subconscious mental model of what a car sounds like so they can be safe as pedestrians and cyclists.
If there were 1000 different sounds, that mental model would never form.
