ELI5: Why do so many racing video games look almost photo realistic when games from other genres don't as much?

Games like Forza, Driveclub, and Project CARS look almost indistinguishable from real life, where so many other games aren't as close. Even some amazing looking games like The Witcher 3, The Last of Us, and Ryse have plenty of things that make it obvious that they are video games.
