Tire and brake particulate is actually a big component of pollution and EVs will cause more pollution from tire and brake debris, which is already a larger portion of pollution than tail pipe emitions. We're increasing one type of pollution and decreasing another type, we'll see if long term it's a net benefit.
Also, they could ban those things in places like SF or more liberal places, however I believe those are politically losing policies and wouldn't pass in places that are actually experiencing obesity.
