I’m with you! Kids in Japan do the same thing, ripping off their carefully designed pipes and blasting away at mega-decibels at all hours of the night in total inconsideration of other people.
Freedom to ride, by all means! Freedom to make a nuisance of yourself and act like a frigging jerk, hell no!
You beat me to it... I was going to say something similar about “bosozoku” .. very annoying..
