Suggestion for Traffic function

An issue is the colors currently used on the screen to indicate rush hour or heavy traffic. These colors almost never match reality. For the live traffic feature to be truly useful, it needs to be far more accurate than it is now.

Additionally, like nearly all other navigation systems, there should be a "road sign" on the screen indicating the specific issue (e.g., an accident or congestion). Ideally, tapping the sign—or having the information displayed directly beneath it—could show the length of any traffic jam.
