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!
Since the sounds are to meet regulatory requirements, I doubt you’ll see ability to use arbitrary noises, at least for the exterior noise.
Good point, the sounds car companies use probably have to be approved by regulators.
