Point taken. There are people out there that take it to an extreme. On the highway, there is no point. In town, in traffic, I know that I have been noticed because of the pipes on my bike and mine aren't very loud at all. My SRT-4 stock exhaust is about the same volume, in fact. On the highway and at speed, even having flashing lights and a wailing siren won't help. I know that and I ride like every car out there is trying to kill me (I'm right more often than wrong on that one). The fact remains that there are more than a few oblivious drivers out there and anything that MIGHT cause them to notice me on my bike is worth a try. The counterpoint to that is that in no way is having a loud stereo aiding in a driver's awareness of what is going on around him and in fact I would argue that it is a hazzard to the safe operation of the vehicle in many cases. I'm not saying that there is no use for having a nice system, but with the sheer number of people prooving that they have no business with a driver's license and driving like dickheads, the last thing they need is another distraction.
