At least that is what they call those cars with loud exhaust. I have noticed over the pass year or two maybe longer this has been an on going issue with these kids and their loud cars. I find it very annoying and irritating to have to deal with this. Law enforcement has their hands full and they do issue citations for these individuals, but it doesn't seem to be much of a deterrent. It's seems like now sitting on the patio and to enjoy a quiet evening is no longer the norm. I live on a busy street, which I have my entire life and the normal traffic isn't really the issue. It's tolerable, but when you get a group of these people at 11pm-3am in the morning doing donuts in the middle of the street by taking over an intersection that definitely ruins the quality of life and is a nuisance. I wish they would increase the amount of the citation to where it would have a financial impact on their wallets or impound the vehicles that are doing these donuts. Do any of you have the same issue where you live. I'm sick and tired of it
