Oh yeah it definitely looks like he was off onto the berm heading for the orange road sign. Either sleepy, drunk, really distracted, or a medical condition. Has to be one of those four I would say.
Once got pulled over by cop because he thought I was a drunk driver. Had to do sobriety tests. I was just distracted..by my mirror..ahem....and my car has always veered right. Dealer claimed cars are suppose to veer right versus left to avoid crash.
