Traffic avoidance algorithm should weigh time saved vs total ETA
Rather often, either when editing, or using the app myself, I see Waze suggest a rather odd route, or down a side street, to attempt to save time on the drive. While laudable in intent, it unfortunately has the side effect of presenting a confusing route or one that doesn't really result in enough time saved vs the amount of time spent driving.
For example, an average driver is probably not going to want to turn off a main route to potentially save one minute to avoid a red light on a one hour drive. Instead of simply using a pre-determined amount of time saved (ie., 30 seconds-1 min) to suggest a detour around a known area of average low traffic speeds, Waze should instead calculate a detour around a low speed route or traffic jam if the time saved exceeds a certain percentage (5-10% at minimum) of the total ETA.
