It's even more insular than it used to be. Saudis used to send their kids to the US to go to college, with Government funding. Now Saudi Arabia has enough educational institutions that they don't do that.

She said it was the only time in her life she'd be allowed to drive on a long car trip. That was decades ago, and Saudi Arabia still doesn't let women drive.
