I know this topic has been discussed before, but I can't find any conclusive answer on the currently shipping version of Model S. Are the reas-seat headrests adjustable or not? I know they were fixed earlier but pictures floating around seems to suggest differently. Including on Teslas own website. Or are those pictures of early versions and this was later changed? Anyone in Europe (I'm in Sweden so EU-version is what matters to me) that can clarify this on an actual European production car? Thanks!
