I've experienced something interesting a few times in high-traffic situations (closed highways/etc) where byways produce time estimates which are instantly implausible as many people attempt to take them. It's interesting to think of methods Waze could use to predict optimal paths while accounting for its own effect on traffic.
Are you sure? Someone just did an interesting analysis (admittedly, very small data space but a long-term test), found that Waze claims faster routes than they typically achieve.
It's entirely possible you're right, but I don't see how on any individual trip you can assert any solution achieved the best time, unless you have 3 different drivers to take each proposed route (and even then, there's enough variability to make it suspect unless you do it over a long enough period of time).
