Doctor Strange reveals that Ghost Rider's power is boundless and godlike, and only limited by the human host. When the spirit of vengeance takes over, the full power is unleashed, but he doesn't continue attacking the Hulk, because the spirit of vengeance avenges only the innocent (which the Illuminati weren't). He also destroys a tank on his way out:
