Displaying Surrounding Traffic In A Vehicle Navigation System

There are websites that can show live freeway speeds, accidents, etc. for US cities.

While doing some investigating into different navigation systems for a vehicle, I noticed something really neat that only European models have. They are able to display traffic and accidents on the navigation map magically (and reroute you to your destination to avoid traffic). So without doing any actual investigation into it, I’m assuming that traffic conditions for a surrounding area are floating around the airwaves for anyone to pick up with the proper hardware.

Now what I want to know is why in the hell don’t we have something cool like that? 🙂
