I questioned the logice behind a rear armrest that behaved the way the Prius one currently does. A friend of mine purchased a new Rav4 earlier this week and his center armrest does not do this. However his center armrest contains the middle seat head restraint. I'm not sure if I like that either. The idea of putting a 3rd person in the back seat of either a Prius or Rav4 is kind of stupid anyway. They might as well make the armrest useful.
