He has to explain to the cop why he was in the car
Well mister you see....
What were you doing in there?
His relationship with his dad and his language (spanish) are part of his culture
I was just sleeping

Don't worry about that power-happy p*ndejo
A meaty faced cop will knock on the windshield.
At the end of your respectful explanation the cop will slowly remove his hand from his gun.
Your pop will be summoned embarrassingly over the loudspeaker.He will say "don't worry about that power-hungry p*ndejo" "You didn't do nothing wrong" and in this moment you will feel closer to your old man than ever before.
