Reminds me of the 2-hole "snake eye" or "pig nose" screw heads you sometimes see in bathrooms or elevators. I have several of the bits for these since they come with every one of those n>20 -piece screwdriver bit sets, but I've never actually had to undo one. I guess that goes for most of the oddball bits those sets come with.
If they really wanted to screw (pun, sorry) with repairability (and at significant cost to themselves), I guess they could start making their own taps and dies for nonstandard threads you can't buy anywhere else. Wouldn't stop them from being unscrewed, though.
Reminded me of the "shim" discussion about BMW motorcycles and part authenticity from the 1974 classic "Zen and the art of motorcycle maintenance": http://www.hilarygallo.com/the-zen-shim-question/
Correct bit for screwdriver available on AliExpress 5 minutes after the bolt is available for public.
I think this is misunderstood - everybody points out that how evil BMW is for trying to be proprietary, then immediately points out any Chinese factory can produce a compatible tool for pennies - which one is it?
I think this is a pretty good mechanical design in general because:
- large contact surface (like hex or torx)
- no chance of slide-out (like flathead) or torque-out (like Philips)
- you can use a different size screw bit than the screw, and it wont slide around, or destroy your nut like torx does with hex
This feels like they want to use trademark law to prevent third-party products. You can't legally produce the screws without baiscally copying the BMW logo onto it. I don't know if a similar argument would hold water for the drivers though.
I'd be interested to know how BMW manufactures those screws. The patterns in the metal in the image suggest the entire hole was drilled out? The deepest part has circular marks inside that looks like the marks left by a facing tool on a lathe or similar. Then I guess the two wedges were inserted and the whole screw faced?
If it's metric thread you only need to unbolt them once, and then you replace them with TORX.
Every time I see that now to me it will represent stupidity and greedy waste
You will be able to buy a "BMW screwdriver" from China in a couple of weeks. This prevents nothing, it's just annoying and goes to show that BMW is run by dickheads (in case you didn't know yet).
Apple's "pentalobe" screws tell you the same about that company.
Wouldn't circumventing trademark lockouts like this be fair use under "Sega v. Accolade"[1]?
Now I’m curious, are there any manufacturers still making repairable cars?

(Their motorcycles had a better rep until now.)
Yet another reason to never own a BMW
BMW resale values make it very clear: these cars are actively hostile (in many many ways) to their owners the second they go out of warranty. Pity, their interiors are lovely. In the long term, is this strategy going to work out for them? I won't buy another one. I know... anecdata :)
