The 300,000 km number also apparently appears in BMW's own carbon ceramic brake literature. I have it in pdf somewhere, it was for the F10, and BMW was basically saying that for a street driven car the CCB's would never need to be replaced, "never" meaning they would last longer than the service life (300,000km/186,000 miles) of the vehicle.

I think it's relatively easy to make a starter motor last to 200K, but not so easy with cylinder walls.
