Understood. And it is like that everywhere. But until people actually do it, Waze will just keep assuming. I believe the base assumption is something like 5 seconds per junction. So Waze thinks it only takes 10 seconds (plus the time to drive the distance) to make the u-turn. So Waze is probably assuming say 30 seconds to take the whole detour. If the traffic light wait AVERAGES out to more than that, well the u-turn is quicker.
Add in the whole 10-minute increments for historical data, and you needs lots of people to take the u-turn at all hours of the day before Waze gets the picture. And most people are smarter than that
