My thinking isn't that everyone will be starting at the same spot, but
rather if there is severe congestion on a main route that the "next
best route" shouldn't always be the one suggested. Specifically, in my
area, the "next best" route might be some local city street, and it
wouldn't take much of the traffic off of a high-capacity expressway to
cause a major traffic jam. And while your right about not being close
to the same fork, since the highway and the city street runs parallel,
you'll still be running into traffic which has been rerouted. (In this
case, sending them to a less optimal route might be a great deal
faster).

I'll concede there is little reason to be concerned given the current
market percentages, but it's still nice to be have a better algorithm.
