I once got out of bed at 11pm to go out and ask the occupants of a car to turn off the engine, the low rumbling noise was irritating me a lot. Was told they were waiting for their SO to come back from the pizzeria with pizzas. I later learned about misophonia but I still hate it when people leave their engines on more than three minutes before leaving.

I wonder what these “be noisy” car people will do as EVs replace aging WRXes etc. we have a neighbor mid 40s age with a teenage daughter, both super nice, both insanely into loud mufflers. It’s annoying to everyone at first but they are so over the top hobby-level crazy about their custom loud mufflers that everyone seems to have replaced irritation with unavoidable amusement. Like there’s a unique set of cartoon characters living a few houses down. They never sit around idling noisily so perhaps it’s the reason they’re tolerable.

Obviously, what they're going to do is blast music really loud.

I don't get when people get into a loud-idling vehicle (probably with some anti-muffling adjustments), start it, and then let it run without moving for half an hour before driving away. Every day. Does their car/truck/suv really take 30 minutes to warm up before it can drive anywhere?

Other times it's loud vehicle sound systems. I imagine the person inside either isn't aware how annoying it is or doesn't care that they're broadcasting bass to the entire neighborhood.
