> Cars aren't nearly as loud as sirens and garbage trucks

Guess what forces emergency vehicles to fire their sirens, or garbage trucks to linger.

bwahaha this is so ridiculous.

You’re really claiming that a congested street isn’t meaningfully more noisy than an uncongested one, including in terms of frequency and duration of horns and sirens?

More noisy? Of course. But even in nice places like Chelsea - at 2am when there are no cars or congestion at all - the cops/ambulances and garbage trucks have no problem being incredibly noisy.

Without cars, emergency vehicles could have their sirens at 10% of the volume. Garbage trucks and busses are slowly being replaced by electric versions which are much quieter.

Electric garbage trucks aren't much quieter. I've heard them. Most of the noise comes from the machinery and the reverse beeping, not the engines.
