Thank you for your diagnosis Dr SaveTheTuaHawk, rest assured I'll give it exactly the amount of weight it deserves.
I'm pretty sure most people find irregularly spaced high-pitched buzzing noises unpleasant; smoke detectors don't play lullabies for a reason.
The lack of engine noise making every road sound and creak from the car audible is a common complaint. Just because EVs are superior, doesn't make them perfect.
