No one seems to really care !
BMW have basically said "Nowt to do with us mate". The OP has been paid out and presumably the OP's insurer will simply write the bike off. It may end up at Copart, where it will be sold and either rebuilt or possibly broken for parts. Further watering down the real issues of why the accident happened in the first place
Maybe next time, when the same things happens again, the rider may be killed resulting in Police accident investigators becoming involved and possibly BMW taking a more serious look in to what actually happened?
For now, it's just a case of, nothing to see here biker mate. Move along
