Waze does distribute redirected traffic if there are other alternatives. I've seen it first hand on the 401 in Toronto; an accident occurred, I was routed one way to clear it and the person beside me had Waze went another way.. 20km later.. we are both back on the 401! Same car, same person, both using Waze.

That's one of the difficulties of commuting the I5 corridor. We're stuck between a huge body of water and a mountain range - there really aren't that many alternatives - and the ones that do exist are already heavily trafficked.
