I have had Waze give me some very good detours, for example driving to northern Michigan on a holiday weekend where there's a ton of traffic, get off the freeway before the massive traffic jam and onto the parallel 55mph highway, then get back on once the jam is cleared. OTOH, it was responsible for getting me my only traffic ticket, for violating a (very hard to spot) no through traffic sign.
