Walt experiences a revelation and a transformation in the car, and the scene is long enough for us to experience it in real time, as Walt experiences it.
The call with Walt Jr. and the Schwartz interview on Charlie Rose left Walt vacant. Everything he worked for is gone. His son has rejected him, he is impotent to help his family, his contribution to Grey Matter was dismissed, and the blue meth empire has continued without him.
I believe that when he rushes out to the car, he does not have a plan - he simply wants to get back to Albuquerque, wreak some havoc, leave in a blaze of glory, and make sure people "Remember My Name." But he immediately finds himself in yet another impossible predicament: surrounded by the police in a car he doesn't own.
In previous episodes, we've enjoyed watching Walt use his wits to escape the inescapable. Here he makes a different choice and "prays" for a reprieve. He says, "just get me home, just get me home. I'll do the rest."
Walt's "prayer" is answered. The police leave, Walt pulls down the visor, and the keys drop onto his lap: a miracle from "heaven."
I don't think this represents an actual religious moment for Walt, but it slows him down and focuses him. He just received a reprieve and now has at most another day or two to finish what he needs to finish and die as whatever kind of human being he wants to be.
He sees his face framed in the rear-view mirror, half lightness and half darkness.
The series has focused on the question of whether the "real Walt" is Heisenberg or the old Walt. I think here Walt realizes that he is both. He come to peace with Heisenberg. The conflict is over and the nature of the work he needs to do in Albuquerque has crystallized.
The "light" Walt loves his family and will do what he can to provide for his son, end Skyler's legal problems, and give Marie closure. The "dark" Walt will take out his enemies and protect the legacy of his empire. Walt embraces both. He admits to Skyler, "I liked it. I was good at it. I was alive. I did it for me." He saves Jesse and finally has a truthful moment with when he asks Jesse to shoot him: "it is what I want."
In this episode, Walt is as calm and unconflicted as we have ever seen him. And when his work is done, he dies blissfully in the lab, the place he did his best work and where he was his most true self.
