So you can sometimes hear them inside the house? That sounds possibly-OK in a sparsely populated area. But in more dense areas with lots of deliveries and people walking outside who can hear all the noise, I'm not sure this will scale well.

I can’t see all the lights on outside from inside my house at night. That doesn’t mean there isn’t a lot of light pollution.

Houses dampen the sound which animals don’t have the luxury of having. All that noise could be a real problem for them

Dude, I think they are very loud. I'm in an office nearby a busy street and I can barely hear the traffic (no special insulation, just regular windows).
