Comparing them to GC mirrors (and many other cars) they protrude from the door so oddly and don't match or line up with anything. Now automotive designers decided to put a small triangular window in the corner, I assume to increase visibility (doubt it makes a difference though I don't think I've driven a car with these mirrors) and stuck the mirror against the door in a goofy fashion. Just my opinion, they don't look good and don't need to not look good. Like going out of your way to make something look worse. The old design wasn't broke, why fix it?

I don't think it's for visibility. I think it's probably so they can make a smaller side window. This way, when the side window is rolled down, it leaves an empty space where you can mount larger speakers. None of those speaker clearance issues we have with the GCs. If they mounted the mirror there, they would end up with a larger side window or a tiny sliver of a glass that doesn't roll down.
That's the only conclusion I could come up with. It's definitely not for visibility.
