Oops yes I forgot The traffic camera codes could be transmitted by the Radio Broadcaster but that would take up a lot more bandwidth and would have to be fairly constant as there are lot more fixed and mobile cameras around than the travel related incidents unless the Nav Comp could cache say 50 miles worth of info

The Nav OS would certainly have to track a lot more objects as well

The whole Nav Comp would probably grind to a halt, it struggles now drawing the maps hence the loss of detail with the latest OS releases.

I would imagine somewhere in a model office or developer land VD0-Dayton Navteq and ITIS holdings have dabbled with it though
