I Really love the idea of actual tools for field sobriety and different "things" that could be used ingame, a bar/nightclub would be awesome and it would give us civilians something to actually do other than cruise around or hangout and one of the few hotspots. I was thinking an intoxication effect to where cars and walking randomly go left and right at random times maybe, and then a way for officers to breathalize you, or maybe even a way to test blood alcohol at the hospital.
