Mario Puzo said this quote

At that moment Sonny noticed that the other car had not kept going but had parked a few feet ahead, still blocking his way. At that same moment his lateral vision caught sight of another man in the darkened tollbooth to his right. But he did not have time to think about that because two men came out of the car parked in front and walked toward him. The toll collector still had not appeared. And then in the fraction of a second before anything actually happened, Santino Corleone he knew he was a dead man. And in that moment his mind was lucid, drained of all violence, as if the hidden fear finally real and present had purified him.
