Some guy driving a Camaro at 0.19 BAC was able to drive in close formation to a pick-up truck and a semi with little chance of causing an accident until he tried to use the median to pass.
What does that say about how incapacitating alcohol is to the driving task?
Well, it seems to have impaired his judgment in just the way that you would expect alcohol to. He got mad at a slight, dangerously tailgated behind another guy (who was also being a jerk), then tried to pass on the shoulder, couldn’t hold the line, and had to swerve into traffic, causing a big wreck. Then, to top it off, he fled the scene, making a felony into 2 or 3 large felonies. Which is what happens when you drink that much and can’t control yourself. Forget the motor skills, which were surely impaired. It’s the judgment, the same thing that makes 300 lb. girls look good at 2am.
