Couldn't find this as a specific suggestion.

I'd like to see two arrows added, one pointing up the other down, with the the number of wazers on the same road ahead within the reporting radius in the up arrow and the number behind in the other arrow. This would be great in determining if you are the 'scout' or have others scouting for you. You might also have the arrows do 'stoplighting' status (Red, Yellow, Green) colors for the user being the scout (red) or other wazers ahead, but beyond reporting radius (yellow).

Thanks for a great application.
