what does the joke mean?

Dear teachers,
the following is a joke about doctors, I don't understand it.
St.Peter was welcoming a new arrival when a red Ferrari driven by a bearded older man in a tweed hat zoomed at full speed through the pearly gates. "Who's that?" asked the new arrival." oh" said St. Peter, "That's God. He thinks he's a doctor."

Does this joke admire doctors or satire doctors? if it satires, what does it satire? and by the way, do Americans like doctor or dislike doctor?

Hello JJ

It satirizes doctors: the idea is that doctors think they're above God, and act as if they were above God.

The joke rests on God's apparent sharing of this assumption: he acts as if he's a doctor.
