What's wrong with that? Does the United States not have US-only roads (that Mexican citizens in Mexico) can't drive on.

Those roads link Areas C. Either you know what that means so I don't need to explain it, or you don't know enough about the agreements between the PA and the state of Israel to discuss this. Just in case you are in the later camp, as I stated, there are Palestinian-only roads in Areas A. Those are found throughout the West Bank, everywhere. Only in a single place exists the Israeli-only road. So the argument about "Jew-only roads" is not only a lie, it is an inversion of true state of affairs.
