You, yes you. Blasting mostly shitty music from your car, it's heard for blocks. You, with the exhaust mods, spewing aural garbage up and down the road.
Look, we know PDX cops have issues. We know they don't have the staff to enforce noise and speeding laws. So you'll continue to pollute our neighborhood with your nonsense for a while. There's not much we can do about it.
But guess what? No one likes you. No one. Be sure that no one ever looks up from their drink, out of their window, or over the shoulder of their companion to remark, "Boy, I love those drivers. Aren't they great? I'd love to meet them," ...said no one, ever.
PS If you're speeding and hit someone, you will have to live with it, even if they don't.
