Three suggestions:

1) Don't ASSume that I crank up the music just because there is a 1000 watt amplifier in my trunk. I may turn it up a little on the highway but never in residential neighborhoods. I strive for quality and not SPL levels. My home theater system has 1800 watts of power. Should I throw it all out because YOU think it's too much?

2) Don't drive in the left lane if you're not going to pass. I don't and I always yield to faster traffic if someone comes up behind me. I expect the same courtesy to be extended to me.

3) If you don't have any anything constructive to say, don't say it at all.

Think someone is trying to give you a hint?
