Over time cabins in vehicles have gotten more isolated with better sound systems. Outside has gotten generally louder. Both of these things mean the emergency sirens need to be even louder for it to get a drivers attention.
I'm not sure if it is because drivers don't hear/see them or if they just don't care anymore, but almost every time I see a firetruck with it's lights and sirens on lately, I see it have to come to a stop and wait, get on the even louder horn, before drivers start getting out of its way. This isn't down the whole length of the street or anything, just once or twice before it drives out of my view (several blocks). I don't think I ever saw in person this before 10 years ago.

Cars aren't loud, car SPEAKERS are loud.
The subway. Ambulances. Construction. Garbage truck compactors. Guys trying to get you into their restaurants. Panhandlers. Buskers. Customers haggling with street vendors. Hassidim on cellphones negotiating deals. Mothers on cellphones giving relationship advice. Laughing teenagers. Drunken couples having fights. Cops chit chatting with each other, or arresting people.
People have recorded the sounds of NYC and during the pandemic someone posted this to YouTube for nostalgia.
I've traveled to 35+ cities and they're all quiet compared with New York.

Why are closed-capital markets in China a sign of a strong American dollar?
Actually the dominance of a currency is harder to challenge, since you can post the same text on both twitter and mastodon, but you can't invest the same money in both dollars and euros.
Not everyone is young and in shape to push couches or jump over them.
