I taught both my sons a simple rule about driving on 2-lane highways:
If ever someone has to pass you on the right, YOU fail as a safe, courteous driver. Your speed is irrelevant - When someone wants by, you let them by. It’s not your job to police the speed of others.
In this case, while I shouldn’t guess about it, I can almost feel the delight from the 18-wheeler driver, knowing that the two of them have boxed the a-hole Camaro in. How easy would it have been for the 18-wheeler driver to lift, momentarily, to allow the Camaro to get by the truck, and therefore contribute to a safer driving environment.
Truckers are taught Smith Driving Principles, and one of them is “Leave yourself an ‘out’.” He has failed in that regard, and shares a small degree of responsibility for the wreck that ruined his day.
Reminds me of a rule of war I just read in Barbara Tuchman's book The Guns of August: "never commit an asset you're not prepared to lose."
