At one point or another, you've probably noticed somebody on the road swerving in between lanes, randomly stomping on his or her brakes, and stopping eight feet past stop signs. Did you lie low and stay behind the person, or did you wait for a safe time and pass said drunky? If you did, have you ever hit a stoplight just to have that person pull up right next to you.
You nervously look out your window to see exactly what you expected: a dude with slobber stains on his shirt, beer cans in the front seat, and a box of three-meat pizza on his lap. Drunk people are unpredictable, dont have control of their cars, and make extremely stupid decisions. If the person doesn't try to put on his best Paul Walker face and race you, get the hell out of that person's way and turn onto a different street ASAP.
