I was reading A Coffin for Dimitrios (great book), and found a character saying “send me a pneumatique when you get to Paris.” And in fact, there was a series of pneumatic tubes to speed the mail in Paris for over 100 years. Thought it was cool. Here’s the wiki as well.
We have had those in parts of Sweden for a long time.
Apparently they were invented in Sweden in the 1960s
But most of Sweden doesn’t have those and we never have trash bags or something on the streets.
