Get impaired off the road first and maybe you'll have a point. And by impaired, I mean by distraction (e.g., phones), drugs, or alcohol.
Wow, are you really so afraid of this in regular every day life that this comes to the top of your mind first when reading an article that is so far removed from the topic of impaired driving??
Wow, if so, then I'd advise you to never get behind the wheel of a car after about 6pm till about 6am, as that there are liquored up folks on the road, lots of them.
I mean, when you drive by those numerous bars, wilth large parking lots filled starting at Happy Hour...and at closing time, are empty, well, I'm guessing you can guess that those folks aren't all designated drivers. And hell, don't come live in New Orleans, I mean, we have drive through daiquiri shops and bars give you plastic "to go" cups here to take your drink to go with you....so, you gotta figure many folks are on the road after imbibing.
