I feel it just varies from state to state, city to city, and population 500 people to, well you get my point. It has been an issue for years I remember one that was from that old douche bag that everyone hated on but that was a while back.
People just don't have common courtesy anymore, it's as simple as that. Just think how only the people who actually care about the hobby read online internet forums. We are just a spec on the whole "audiophile" spectrum. My point is, the people who drive by neighborhoods and disrupt everyone will never change unless some sort of enforcement is going on.
What they should do is just start being more harsh on the situation. If there is someone who regularly drives by being an ass hat then take his license plate, or any other valuable information and fine the **** out of him. Because the vast majority of this thread agrees with what the man says its just no one is thinking clearly enough to make a "reasonable" decision. We should not leave it up to the older people who sit around and have nothing else to do but bicker about the worlds problems.
I stand by the older guy and the forum members about it being a problem. But I will never keep quiet about them completely banning audio systems. Something does need to be done though, gives us a bad name.
