Personally it's a toss up between the "la di dah" and just not paying attention...which can be combined with the last second "3, 2 1 Don't Walk countdown...but can still make 'em"  On top of that, the consequence of the motorist (1) (obeying the law) waiting to make the right turn as "la di dah, not paying attention" meanders across.  Motorist (1) cannot complete turn because red light activates and it's "No Right Turn on Red"!  Motorist (2) in the back of motorist (1) is trying to get his kids to school honking his/her horn to hurry up???  I could recommend a solution but motorist(1) would be arrested for manslaughter. :)  Just saying....
