Okay, everyone. I've read this whole thread and you all need a different viewpoint. So here's mine - albeit a philosophical one.

There is no such thing as luck. You make your own karma by the actions you choose. Every action has a reaction and every reaction is also an action to cause other reactions. To put it simply, only you can cause your own suffering and your own happiness. Nobody else can take either blame or credit for your life but you.

If this story is true, and I am not even going to try and answer that, the BMW driver caused his own suffering. Granted, maybe there was something Carlton could have done to gain merit on this by looking out for other drivers to come behind him, but it was (is) not necessary, if the conditions are not present for him to do so. And from the sounds of it, he wouldn't have had that opportunity in this case.

So, Carlton was in the right by making the choice he made at the time - i.e., to avoid putting himself in danger (by hitting the log or possibly running off the road to avoid it). The BMW driver on the other hand made a bad choice and suffered the consequences - just as the Law of Karma requires - immediate and proportionate retribution for his deeds. If you understand this simple law, you can sit back and watch it happen all the time and it can be very interesting to watch too.

End of story.
