Large-diameter tube freight has, a history.[1] The USSR built a few sizable TRANSPROGRESS tube systems with diameters in the 1.5 to 2 meter range in the 1970s. Mostly for garbage disposal. There have been proposals on and off for over a century.

Pneumatic garbage disposal is in use in a very few places. Roosevelt Island in New York has had a working system since the 1980s. It works well and is well-liked. Roosevelt Island was supposed to be car-free, and lacks much of a road system, so this was a good fit.

The anti-car crowd should be pushing for this.
