What is the significance of Kafuku's reaction to sitting in the passenger seat of his Saab after 12 years of driving?

It is interesting that Kafuku so quickly embraces the fresh perspective afforded him by hiring a driver. Rather than feeling emasculated by his inability to drive his own beloved Saab when a DUI and glaucoma diagnosis result in his license being revoked, Kafuku seizes the opportunity to relish a new view of life. The narrator states, "After years behind the wheel, the view from where he now sat seemed fresh and new" (10). His outlook indicates that he is open to the idea of transition and change within his everyday life.
