Cycling as a competitive sport on the road is well over a century old, the peloton is where it lives.
Riding a paceline is integral to peloton dynamics whether it's a few teammates out for conversational early season base miles or the lead out to the high speed sprint finish in a sanctioned road race.

Paceline riding when done properly is a highly disciplined co-operative effort demanding skill, technique and experience. In my day these were provided by nationally sanctioned cycle racing clubs that held regular club rides to hone those skills with structure and purpose.
Good clubs foster skills at all levels. "New rider" rides were available to ease entry to the etiquette and complex dynamics of the paceline as well as full-on training races for the experienced teammates to do their thing.

Great fun, but not for the un-committed: membership, and proper safe equipment was required.
