I'm starting to think we all live in the same neighborhood...

I just commented on another post about a retiree who dual-wields gas powered leaf blowers down the street from us, but it looks like you already know him and have to deal with it...I'm so sorry. As a side note, there is a house across the street from him, and slightly down the road toward the cul-de-sac, that emits a very high pitched whine that my wife and I have noticed for years. Ever heard it/dealt with it? Most of the people in that neighborhood are too old to hear it and it drives us nuts when we walk by...

Imagine the government maintaining that you need mufflers or catalytic converters on your vehicle due to air and noise pollution...oh wait.

"A 2011 study showed that a leaf blower emits nearly 300 times the amount of air pollutants as a pickup truck. Similarly, a 2001 study showed that one hour using a gas-powered lawn mower is equivalent to driving a car 100 miles" https://sustainability.wustl.edu/rethinking-lawn-equipment-2/#:~:text=A%202011%20study%20showed%20that,driving%20a%20car%20100%20miles.
