I’m one of the people who lived next to one of these roads. While there’s no doubt that motorcycles and muffler-less vehicles contribute, what wears you down is the absolute constant noise of all traffic, you cannot escape it. Forget being worried about waking up from random loud motorcycles or jake braking, you couldn’t get to sleep from the sounds of car tires coming and going (Doppler effect). Just when you think there’s a lull and some relief, the roaring is back. It’s torture and unbearably depressing.

I also studied noise pollution in depth for my degree, so I’m really not in denial about anything. I actually know way more about this topic than most people.
