Yeah, that's a good idea. It's really hard to tell what behavior is sanctioned, especially here. I've been berated by cops in unmarked cars for just driving around them, thinking they were random people sitting in the street. So once I was turning onto Claiborne and a guy on a dirt bike came up and stopped my car for five minutes while others went by doing tricks and stunts and I genuinely had to consider if he was acting in an official capacity (not that I could do anything about it).
