Here's a better Q: What in God's name is going on inside the mind of drivers who "cross over" smack in2 opposing traffic? This isn't something that occurs in milliseconds. If you were 2 deliberately cross over, it'd still take 2 seconds 2 occur unless you deliberately made as sharp an angle as possible. But "drifting" or "crossing" by accident surely takes 2 or 3 seconds IF the median is wide like on 470 -- enough time for the idiot driver to correct this unless they are unconscious or having a stroke/heart attack. I doubt most of these cases are sudden-onset medical episodes like seizures. So what is WRONG with these fools? What does it take to realize you just drifted over--the head-on collision? Can't they SEE their vehicle is drifting over & correct this in time? Or is their brain so defective that they can't process the situation fast enough? Or are 100 percent of these idiots in a deep sleep or drunk? I've driven while drowsy and NEVER drifted. Never been drunk, either.
