It's along the same lines as blaring the car radio with the windows open while driving into a neighborhood. Heck, my neighbors do this at 2am, then sit outside, with the car radio still on, full blast, and talk for an hour or so.
IME talking to them does nothing. They feel they are entitled and they flat out do not care if they are bothering anyone else.
One would think that when they move into a neighborhood and notice that no one else acts like this, they would change their ways. Of course, that would take some self-awareness...nevermind...
I had a neighbor whose driveway was about 15 feet from our bedroom window. He worked weird shifts and would sometimes leave at 4:00 in the morning. That didn't stop him from warming up his truck for 20 minutes with talk radio on full blast. This was the same guy who started his home remodeling projects at 6:00 am on the weekends. We told him we had to put our son to bed earlier on the weekends because he was waking up to the circular saw outside his window, and the neighbor just smiled and said, "Is that right?" It was weird because he was otherwise a fantastic neighbor. He just had no awareness of how much he was disturbing his neighbors.
