That said, no car is really loud sub ~3000 rpm, at least not in the way I imagine you're implying. That is all this (or most any) car would need to muster for driving down the streets of London or any city.
The problem is that some owners get really aggressive with the throttle in places they really shouldn't. I'm with you, that is annoying, but that is by no means an isolated "super fancy car" problem. Motorbikes, modified scooters, tuner cars, trucks tuned for show instead of work.
This whole thing is about how some folks can't help but flaunt their opulence/excess. Talking it out on the car is like talking down to Tesla for including autopilot knowing that some drunk drivers will simply use the feature to take themselves home.
