Long group rides work better with stretches without intersections that the organizers have to pay to have policed.

And this:

Those quiet, winding country roads with no traffic won't stay quiet and traffic-free if everyone knows about them.

For me, I get my hard training (and racing) done on Zwift. When I'm riding outside (almost never after getting hit last spring), I like to go for meandering rides where I can enjoy the scenery since worrying about traffic and all the stops and starts of intersections means I can't focus on getting a solid continuous workout in.
