Could increased street sweeping help?

[ravenstine]

If performed correctly, maybe. I'm not convinced that street sweeping in most cities much but a low-level scam so the city can cash in on parking violations. In LA, I've seen street sweepers my whole life going around and mostly kicking around dry material and moving so fast that they barely pick up anything, often followed by a parking enforcer some kind of golf cart type vehicle. Street sweeping makes more sense when the debris is big and wet enough to be swept up, which may not be the case for most tire debris. If it's tire particulate, street sweeping might make things worse by making it more airborne.

I’d almost guarantee the bristles on a street sweeper are also leaching insane amounts of toxic crap into the environment. I bet they’re plastic…

They are metal, you find them in the road sometimes.

[basil-rash]

They’re metal. Plastic would not stand up to the task.

They're actually steel, and if you keep an eye out you can find them all over the place.
