I know everyone hates HOAs because they're usually petty and dumb, but this is where I think they'd actually be helpful. Designate certain neighborhoods as "quiet zones" where similarly obnoxious activities (that have reasonable, quiet alternatives) are banned: no motorized leaf blowers, lawn mowers, souped-up motorcycles or muscle cars. If you want to own one of those things, don't move into that neighborhood.

I've come to realize many people feel "forced" to move to incredibly space- and resource-inefficient (and thereby ecologically-damaging) places like suburbs and exurbs for basically two reasons: better schools, and in an attempt to escape asshole neighbors. Sometimes it's so that they can themselves be the asshole neighbors, but generally people are trying to live in a "nice" neighborhood not over usual HOA things like house siding color and properly-concealed trash cans, but rather for a general desire for peace and quiet. I know I dream about living on 40 acres not so I can start a dairy farm, but to escape the various forms of pollution (primarily noise, air, and light) emitted by my current neighbors. But I wouldn't feel the need to do that if my neighbors had similar desires as I and limited things like car idling, porch lights, and landscape-related noise. Meanwhile the neighbors upset at me for keeping my yard wild to support wildlife could have a neighbor with similarly bland yard maintenance standards.
