just a thought: The only reason we have so many pics of this is because of probably the nature of the accident leading to severe injury, the car being rare enough that whoever could, took pics and the fact that it is a very traceable car (colour, spec, numbered) etc etc. BMW will also probably know exactly which car this is and it ended up at an ARC where they will have immediately suspended the plan pending repairs. Airbags blowing while you have connected drive active will also trigger this (if your car is out of service then you'd probably also get away somehow with this)
For your joe soap cars or cars involved in accidents where the owner/driver is in control, it is entirely possible to have the car taken to be assessed at a Non BMW repair centre, have it totalled by your insurance, but off BMWs books and then (still without comments) someone can buy it at auction, repair it and sell it as a no comments car. We as consumers have no view (still in 2023) of this.
I mentioned in another post that there are exotics where exactly this happens. Even the transporter is a private job, car is wrapped up for transport. Some carry a comment if Ferrari has to order a cradle or certain specific parts that must be tied to the VIN, but you often have NO IDEA of what the damage actually was, how much it cost to repair and there are some cars where even the story of the accident changes as the car passes between dealers. There's one car where I've heard the son drove it through a wall and it was 'only' R800K and another where the same car was driven off the road by someone else and it was a R1.2M bill and still a third at one of the infamous east rand dealers where the car was sitting with even more codes than before and they said nah it was a small prang when someone drove into it while the car was parked 'just a bumper on these cars can be 600K'

.
THIS is the problem with no comments cars that have obviously been repaired...
