> I hadn’t heard that NIMBY’s are also NOMS (not on my streets) but it doesn’t surprise me they’re trying to keep cars from driving down the public streets they live on. Is there anything the affluent won’t do to try to exclude themselves from society at large?

What does this have to do with affluence? As far as I know, this affects people who live near a congested major road but do not themselves live on a congested road. I’ve seen it in rich and poor neighborhoods.

It actually seems like it may affect less wealthy people more. Wealthy kids seem less likely in general to play in the streets. “I want to live on a street that isn’t full of cars” is an entirely reasonable sentiment and has little or nothing to do with wanting to exclude outsiders from one’s street.
