Well, BMW and most other ICE makers are in an impossible economic scenario: they have a pipeline of investments focused on making millions of ICE cars, which investments must earn back their costs, i.e. all those ICE cars must all be sold, and at the expected profit margins.
That pipeline of ICE investments has expected depreciation schedules of 5-10 years.
These ICE companies have huge inertia, with an annual new capacity of maybe 5%. They cannot convert to EVs faster, especially if there's a collapse in ICE demand. And they absolutely must not write off hundreds of billions of dollars worth of obsolete ICE factories...
Another problem ICE manufacturers like BMW have is that they have one core competency, one big competitive advantage: the internal combustion engine and powertrain and patent moats around them. They are outsourcing even the assembly line for premium cars, not to mention R&D.
So if you take away the ICE powertrain, what is left? Not much ...
That's the "ICE paradox", in a nutshell.
