i hate oversensitive neighbors but trust me, when i had an infant in the house that HAD to sleep there's a definite line of what amount of noise i was willing to tolerate as "normal" (although that was an HOA neighborhood). it doesn't sound like they're anything more than just annoyed that you're disrupting their special little world though. might be worth just idling down the road once you get moving to keep them from starting to call the cops on you for noise violations.
