There's a good reason for this

There are two reason for this. One, high beams actually decrease visibility in fog. The increased illumination reflects off of the fog and makes visibility worse. Don't believe me? Find an older car that will allow this and try it for yourself. I did, years ago. I didn't learn this from the link below. I discovered this for myself decades ago and just now looked for supporting documentation to corroborate my findings. Two, in most states it's illegal to drive with fog lights and high beams on simultaneously. I assume that's because of reason #1 and the blinding affect for oncoming traffic.

Sometimes MB gets it right with their designed features. Sometimes they don't. In this case, it would be the former.

Oh I agree and knew that. High beams are bad in fog. But I just didn't know that MB took this into consideration when designing the feature and since I'm now even closer to being out of warranty, every little bump, snap, and pop I over exaggerate.
