Headlights On While Backing In A Truckstop

You already answer your own question.

 

What afraid someone might see you watching your porn

 

The same ones that don't know what hazards when backing are for, if I turn off my headlights, my DRL's kick on if my brakes are released.

 

"Dim the lights"???? What do you mean "dim"? You say that as if there is another option?

 

dim the lights, dimwitted drivers

 

How about the ones that leave their headlights on while they sleep?
I had a Volvo turn their headlights and fog lights on when I was starting to back in next to them. Watched him close the curtain and still have his headlights on. I think after the 4th pull up, due to being blinded, I finally decided to have to turn his headlights off.
People like that go in the same category as those who flash their high beams when you are clear to come over.
Better yet, join them with the 62 mph trucks that don't understand passing etiquette on a hill.......
