You can be busted for riding a bicycle with an open beer in most American states.
However, in South Carolina, you can usually talk the officer out of a DUI and into letting you just pour the beer out - as long as you haven’t hurt anyone, you have (or can fake) a local accent, and you don’t get “uppity”. Standards of what constitutes “uppity” depend on the officer more than on the skin color or gender of the perp, but as Scalzi says, straight white male is by far the lowest difficulty level to play on.
If you are the Mayor it might be OK to get uppity… depends on what the relationship’s like between the local police chief and City Hall.
