> That said, no car is really loud sub ~3000 rpm, at least not in the way I imagine you're implying.

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.
