Long stoplight waits need a special alert
I have an idea for a different and useful alert. Sometimes you come upon an abnormally long line of cars waiting at a red light, so it takes several light cycles to get through the intersection. You know, when you're on a road you know, and you're stopped unexpectedly, then you realize that it's because of a light that never gets that much backup.
Being stuck there for several light cycles can have a significant effect on the total time of your trip, which Waze can't calculate because it has no idea this situation exists because there's no alert like that. People don't mark this as heavy or standstill traffic because it's not traffic, it's just cars waiting at a light.
If there's a way to create this kind of alert that will factor in with your total trip time, I think it would be super useful.
