Occasionally it’s just the driver’s lack of familiarity with the road. I once found myself in this situation in the KC suburbs. It was very dark, and I took a left turn at a stop sign onto what I thought was a two lane street. Turned it had four lanes with a very low curb in the middle. After a couple of oncoming cars flashed their bright lights at me, I realized my mistake and drove over the curb into the correct lane. I was cold sober in an strange part of town, and it scared the crap of out me. Thank goodness traffic was very light.
Not in this case. Were talking well lit super highways with world class signage. I know this area well. You could read a newspaper standing in the #1 lane at midnight. But I wouldn't recommend it. Anyone confused at this venue should never be behind the wheel in the first place.
