They follow devoutly the way of life of the founder of Islam. As Muhammed lived they follow his example, literally. The mindset is still seventh century, but modern inventions/ convenience is allowed only as it will further Islam. Example: years ago read about some jet used by a Saudi king or prince, his seat in the jet would always calibrate direction it faced towards Mecca. Also, they don't play. Their punishments follow dictates of Sharia law and they are not ones to be concerned how others take it. As it is apostasy to have personal relationship with their god, reflecting the life of the founder is as close as they can get. Innovation comes slow, but the mindset is not amenable to change. Strong resistance to reform as that could seem blasphemous to the devout.
