No worries about the Hi Jack's fella's.
If I remember there was some talk about coming down hard on classic car enthusiasts/modifiers/tuners in the Uk a while ago. It will take a brave and stupid politician to try to implement any drastic changes, its a big industry with lots of followers and livelyhoods involved. for this reason I can't see anything too drastic happening. But I think the noise issues are quite rightly founded if its out of hand, noise is a pollution at the end of the day and its not pleasant, a bit like Death Metal
