Actually, I met a cop that drives a Black 2g TSi.
Really cool guy. We were both at NoyzBoyz and he was just getting something done. He just got a 2.25 catback and we drove each others cars. His was nice and soft and civilized. Mine was noisy and harsh and spinning. Talked about being a car enthusiast and a cop at the same time. He's not on the traffic scene anymore. He's in Narcotics. Said that when he was though, he'd just sit and talk to the guys and then leave. If you're in a back road somewhere, and you just chill when they arrive they'll most likely go away.
This was a few years ago though. In any case, running for the hills is a bad idea.
