Seat improvements? I noticed in the Oslo townhall meeting with Elon Musk that when he talked about improvements to the seats he said that one part of the improvements would probably go into production in the next week or two. As my car has just started building today, I'm wondering what the improvement is and whether it will be part of my car. Does anyone have any insights or further knowledge of this? I haven't re-listened to the video so it's possible I've extrapolated what Elon actually said into something more meaningful than was intended.
