My neighborhood is spooky quiet, so I hold off on lawn mower, leaf blower, other noise until 9 AM just to make sure I don’t disturb anyone.

I have noticed someone the next street over who has apparently set his rule at 8:30 Sat to fire up his lawn mower.

I think you’ll get a harsher reaction starting a non-necessity like a motorcycle early in the day than you would a necessity like a lawn mower.
