Think local councils probably make it a requirement for the road closing in those situations.
June 2016 Taranaki Tarmac rally in New Zealand used virtual chicances to reduce average speeds on some long straights. Prior to event many competitors expressed doubts about how it would work, on the day it seemed to work really well. Because they were in middle of long straights it did not affect spectating opportunities. You can experience a virtual chicane between 1:19 and 1:23 of this onboard video https://www.youtube.com/watch?v=n44SFcXxUwM
