Fine. But the broader point is that the customer is the product, not the owner of a purchase.

The head was almost certainly milled out of a blank made on a lathe. Something like this: https://youtube.com/shorts/Yf-twqgWZQ8

CNC Milled and suface brushed. I Think these screws are going to be used in some decorative Panels etc. Would be cost prohibitive to use these all over the Car.

Those are end mill marks.

A friend of mine used to buy the first model of any new and hot BMW. He'd know the specs better than the sales people and he spent a fortune on them.

They also spent more time in the shop with electrical gremlins than any car that I've ever seen. One of our employees insisted on a Mini, which is also BMW as their lease car. No other car we had had that much trouble. BMW is a crap brand that used to make very good cars. Mercedes is getting there. Neither of these will survive in the longer term if they don't somehow get back to their roots: making safe and reliable vehicles with good resale value. But for both companies the problems are in the same domain: they never got the hang of software.

Probably more of a gimmick than a strategy. In the grand scheme of things in cars a pretty minor one too. Replacing a panel and a bolt vs. replacing more complex components that have proprietary firmware, wiring harnesses, 3d printed/molded components with very complex design and tolerances, etc. A lot of that is business as usual across the industry.

The key issue here is that repairability is currently not really factored into the sales value of the car. That's a bit naive of course because it actually does impact the second hand value of a car. For example, MG makes nice cars but they have a bit of a reputation for needing lots of repairs under warranty. That reduces their second hand value and therefore also impacts their new value. You can get some really good deals on second hand ones. But the repairs might add up. That's why the second hand value is so low.

Lease companies buying new BMWs to lease them out to high salaried executives expect to be able to sell these things on 3-5 years later and get a decent second hand value. If the car then has a reputation for being a bit difficult and expensive to work on (like MG), that is going to reflect in the second hand price. And the lease price. Mostly lease companies just pass that on in the lease price. That works for BMW until more competitive vehicles show up that can be leased at a lower cost.

A few quirky bolts won't move the needle here. They aren't going to get rich selling them or the tools that go with them. It's just a bit of minor friction for car repair shops. If they see enough BMWs in their shop, they'll get the damn screws and tools. It's not that different than Apple using custom screws on their devices. Every phone repair shop has the tools now.
