Especially considering the alternative people are coming from is a loud very noisy machine with lots of moving parts, the fact it makes any sounds is probably not a big deal in the sum of things. Maybe eventually as everyone is in EVs this will be something people notice/care about in a competitive product way and you could or try to eliminate or shape the sounds to be more pleasing beyond. It’d probably make iteration more expensive if it became a requirement.

Most of the time they operate with lots of ambient noise of the tires on the road and outside the car which probably makes a lot of these barely audible or noticeable.
