It won't pass. It's more of an attempt to draw attention to the "issue." Just people driving around bumping their shit in traffic, through residential areas, in the middle of the night, etc. Look all over the internet and you'll find thousands of stories of people bitching about noise pollution while people are still hauling ass around on their Harley's. People like that give us real audio enthusiasts a bad name. I love and enjoy the hobby, the challenge, and the reward at the end...
The bills has way too many obvious holes, and as I said, is just really a call for attention...
Have a read at a good letter of concern written in regards to the bill...
