The latest developer diary for Driver: San Francisco discusses the role of protagonist John Tanner, absent from the series since Driver 3. In the video, he's described as an "historic, iconic" character. That may well be, but he's got nothing on the real San Francisco Tanners.
Gamers fill the role of original series protagonist John Tanner, who is in the unfortunate position of being totally comatose. The game takes place in his mind, giving him the ability to change his dream reality to his will. Tanner must have a photographic memory, as the game will include a roster of over 100 licensed cars.
