Driving behind a Mafia guy

Sorry, I didn't take a photo... but the other day while driving I was stuck in heavy traffic, that was hardly moving. I noticed what looked like a Mafia car, stopped in a narrow laneway, trying to merge with the heavy traffic. I pulled up and let him in, he bowed to me and waved! That was pretty cool. Until I realised that I was stuck in stop and go traffic, directly behind a very expensive looking black car with solid black windows! I kept my distance for the next couple of kilometers, although I was watching his brake lights intently!
