Recently, Steven Troughton-Smith has shared some info about getting iOS in the Car inside iOS Simulator. Steve, however, declined to share instructions on how to get this working (because it's quite hard to enable this mode on iOS 7.0.x builds).

So below is something I've come up with for iOS 7.1 beta. It's lot easier to get iOS in the Car enabled there.

Before you try to break something:

  • It's unofficial
  • It's quite unstable

Three steps to get iOS in the Car up and running:

  • Get Xcode 5.1 DP2 (it was tested with DP2, and doesn't seem to work correctly with other developer previews)
  • Clone
  • Build & Run cloned project and carefully follow instructions

Use Hardware > External Displays iOS Simulator menu to disable iOS in the Car.

UPDATE for other DPs

It seems that iOS in the Car is not working properly with other developer preview versions of Xcode 5.1. DP1 - no iOS in the Car at all, DP3 and DP4 - window is shown, but only sidebar is present on screen. Please try things with Xcode 5.1 DP2.
