Response blindness

what’s happening during the first scene is that a second person has now gone blind. The first man that just went blind was the old man in which he was on his way home being helped by a stranger. When the stranger initially offered to help the first blind man, he had no intention of stealing his car. The idea had come to him when he dropped the blind man off at home and hurried the car thief out the door without asking for the keys back. Perhaps if the first blind man had allowed the car thief to stay, he would have been overwhelmed by his conscience and wouldn't have stolen the car. In any event, the car thief is driving around the city, nerve wracked in an attempt to avoid the police, when he decides to park the car and wait. As soon as he gets out of the car he goes blind.
