You're not getting it. If I want to know if a particular route I want to take has traffic on it or not, I would much rather have the map explicitly show me there isn't traffic than have it show me nothing at all and leave me no better off than before I opened the maps app - especially if I am in an unknown-to-me area.
Oh I got it. Sounds like yr not getting it. Sounds like yr having trouble adapting. Traffic is the anomaly not free-flowing movement. Traffic is what needs to be reported not an open highway. Like I said maybe not the best implementation but it works and if you don't understand it that's your issue.
