What to do when a demigod flashes his bright lights from the rear at you when driving?
The answer is post it in the speed limit signs. Just keep on driving at your normal speed and wave him with your hand in a friendly manner. That will get his attention and attitude with a road raging maneuvers sparking of a demigod being piss at you.
When he pass you, just smile and stare at him like you don't Care!
Because you are just another demigod.
