If high revs on a cold engine caused fast bearing destruction, every rental vehicle on earth would spin bearings monthly.

The rotating assembly in an S65 follows the same laws of physics that a Honda/Toyoya/Mazda/Ford/Chev/Volvo does. If bearings are properly designed, they are not fragile. If the oiling system is designed properly, then cold running will not damage bearings because all you need is flow to make the bearings work.

No, I do not propose that you flog your engine while cold. It is good practice to warm it up. But BMW limits the cold RPM redline to a value that will protect the engine so there is no way that the damage we see can be consistently attributed to cold engines at high loading.
