I love Google Navigation. I think it does an excellent job. However, I would ALSO like to see an overlay of (a) traffic, and (b) red light cameras (which they are just starting to install in my city). Obviously I can use Google Nav on its own, and I can use an app like Trapster on its own, but I can't find a way to use them in conjunction. I want (a) to see my turn-by-turn directions to get somewhere, and (b) while following those directions, see that I am approaching a red light camera and/or heavy traffic. I realize that I can probably see traffic in Google Nav... so maybe that point is moot... but is there any way I can see ALL of these things at once? Thanks.
