C’mon up to the Northeast and add blinding, accumulating, unplowed snow to the mix. I do many trips between Maine and Mass. and inevitably it happens once a winter or so.
The highways become black thanks to lights being removed many years ago and you can't slow down also due to the fear of losing traction on a low grade hill. Add to that 18 wheelers still moving like it's a summer day and it's just a blast.
The thing about fog is, many times it comes without warning. I know sometimes blizzards do happen unexpectedly, but usually there is some warning.
