Motorcycle Groups being Dicks

I live at the apartment building across from the Straz. Within the last hour, a group of 40-60 street bikes all gathered in the access road and decided to bounce off the rev limiter in a coordinated display of jackassery.

Why does this happen? What sort of narcissism must you have to coordinate a takeover of a public street just to piss off everyone that lives there? How exactly does this serve you?

Never once have any of the car clubs I've been a part of expressed a desire to go meet up somewhere specifically to be a burden to other people.

What sort of mentality thinks this is a fun thing to do?
