If in the air for many hours (which seems to be an accepted fact now), then on the course to Pulau Perak, if it carried on, then the plane must have flown over Northern Sumatra - through Indonesian airspace. The Indonesians would have seen it.
This assumes everyone is telling the whole truth, which I'm sure is not the case. There seems to be various kinds of misleading going on, with Thai authorities only now releasing their radar information because "no-one asked for it specifically". And some of the earlier Chinese photos "should not have been released".
For example, "for reasons of national security" Indonesia won't want to tell Malaysia (or Australia or anyone else) the extent of their radar coverage. Especially if they are doing something illegal/immoral/extremely clever to achieve it. So they may choose to NOT tell anyone if they saw the plane fly over their territory.
If it turned right when it was over Pulau Perak - as suggested (and generally accepted) did happen - then somebody was at the controls.
To be pedantically accurate... the autopilot *could* be programmed to follow a path from one waypoint to the next to the next, so it could have made the right turn. Although programming it that way in this case doesn't make any sense at all.
