Yes, I can confirm that the caulk is applied by robot after seeing this in some BMW production videos (I wish I could remember where I saw that). Where the caulk is straight, it's way straighter and more uniform than a human could do it, and where it's back-filled, it's done in a repeatable pattern no human could do. Go back to the picture I posted on page 1 of my Z4's caulk, and you can see a back-fill pattern very clearly.
