Right, so we've worked that out. Now we need to work out what the "interior viewpoint" is!

I personally believe this is going to be different angles of the interior, like in the Ferrari 458 videos. So for example, a camera behind the passenger seat, one in the footwell, drivers point of view. Otherwise, what's the point of recreating the interiors down to the stitch if we'll only be able to see them from the drivers point of view?
Also, another possibility touches on what you define interior as. I have seen several videos of car with cameras mounted in the wheel arches, looking at the suspension working, cameras underneath the car looking backwards and cameras pointed at the exhausts. Just a thought

As with most of this thread, this is all speculation. However, I'm yet to see an official PD/Sony source say 'there will be no cockpits for standard cars' (Notice I said cockpit, not interior!)
So, until then, I'm going to keep the faith! I've never been around so many pessimists! Kaz hasn't let us down so far!
