The car is drivable, but I would not say everything is working. As basically now it is a dumb car without cameras (the view from rear window is really small), without automatic wipers, without auto headlights, without navigation, without dimmable mirrors, without battery preheating for SuC, without any safety (anti-collision) features and without TACC or basic autopilot. I am going for a long trip at the end of the month, hopefully it will be fixed until them.
Service request is opened since last Tuesday, on Thursday I noticed my seat was in a different position (could it be related to Tesla doing something remotely?), hopefully the car knew it and I was able to "Restore" the position from my profile, but it took me few minutes to realize something is not right
Today I asked for an update, got almost instant reply that they are diagnosing and it could take "some time"... I hope it doesn't mean keep the case in pending until a new software update is generally available...
