I'm not a rich guy, and I don't find it to be a nuisance in most circumstances; I appreciate the sound of high performance engines, and so do many other people.
can imagine non car people getting at least as mad, at louder cars.
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.
As someone who loves cars, I wildly disagree. There are modded cars that idle across the street that wake me up through my double-paned windows. A very popular mod is to add a downpipe to some cars, which is illegal in California (for emissions reasons), but people still do it and holy fuck it is just so god damn loud. It's great at the race track, not so great when you want to sleep. Sometimes cars are just loud and obnoxious.
In a past life, I had a '69 Ford 250 with a big-block 390 that would beg to differ... but it got between 4 and 6 mpg so even in 2001 that was too expensive to keep...
outside of hn, I've never really encountered anyone who was more than mildly annoyed by loud exhausts.
