^This. 100%.
But it's not just kids. 50-60yr old one street over bought a C8 back in May. Looks great, sounded great. June comes around and he's got a new exhaust. Now he's flying up and down MY street doing around 80mph before he lets off and blaps the 1/4 mile down to the stop sign. From the fumes, I'm guessing he's catless now. In any case, it's now so loud and sharp that it hurts my ears INSIDE MY OWN HOME WITH THE WINDOWS CLOSED and I have have 20%/40% hearing loss from a few years working as a DJ and weekend weapons fire w/o earplugs.
Add to that, not only is the usual speed limit 25 for residential streets, there's a pre-K/K & park, a daycare in the middle and disabled childrens home (mostly cerebral palsey) on the other end.
That's the worst offender, but there are about a dozen others that use my street since it's connects theirs w/ a major artery that goes to the freeway. It's gotten so bad that my neighbors tried to petition for speed humps to be put in but the public works office denied it. I know that at least one person has called the cops on the C8 when he's flying up and down the street continuously for no real reason while kids are playing outside.
Sorry for the rant. It's annoying when the idiots ruin things for everyone else.
