Sean, is anyone ever responsible for thier own actions in your world? The guy in the BMW is TOTALLY at fault. He was the one tailgating. He was the one driving irresponsibly. He was the one playing a dangerous game on a one lane highway. It is not Carlton's job to to be nursemaid for other drivers on the road. What the BMW should have done was back off. End of story. No excuses. Why should Carlton put himself in danger by stopping or pulling off on a small or non-existant shoulder just to let this asshole by? The safest play for him was to go over the log, he knew he had the clearance. Why should endanger himself by trying to go around it? He could lose control on the shoulder, or worse, could have endangered oncoming traffic.
It was no ones fault but the BMW driver for following too close. There is no excuse. Karma can be a beautiful thing.
