For those who use cars:
* If you are going to play music in your car, *please* keep your windows rolled up, so I don't have to hear your music (which is probably of a type I can't stand).
* If you are going to roll down your windows, *please* refrain from playing music in the car.
I felt like you for a long, long time. The louder the music, and the more money they put into subs, the more I hated driving next to them.
I installed subs and I'd like to give you a little bit of perspective.
First, people who do this are not usually trying to bother everyone else around them. My mother loves rolling down ALL the windows and turning up the music as loud as it can get and singing along. It's just her way of relaxing (or waking up if she's driving late at night).
Second, if you have subs, you understand what I'm saying, but if you don't roll down your windows at least slightly, all the subs do is make your car shake and you lose a ton of fidelity. I believe it comes from the physics of the wavelength of such low frequency sounds, usually longer than the interior of the car. Some people do this to "share" their music, but the only times I roll down my windows are when it actually changes the sound quality of the lower range significantly. Maybe you can't notice, but I do.
Perhaps play a little bit of music when you drive and you won't hear anything? You'd be surprised
EDIT: Oops, ended the post without ending my thought. You'd be surprised at how well a little bit of music isolates yourself from the outside world's sounds.
