Because their MMI was designed by mechanical engineers who don't actually have large software distribution experience, so they designed the firmware update to trickle in through a small straw, and not be available over the air.

Chances are, they don't even have a second partition with the next-to-latest update firmware on it, to switch back to if the next update fails. I bet they saved a whole dollar on internal flash storage with that decision ...

That's not exactly true, i'm not that familiar with what their exact process is but VW corp. has a development center here in the SF Bay Area that is most likely developing MMI PCM and the VW brand stuff all together (Called IECC)
If someone has more insight to that place it would be nice to hear but to me it looks like they have all the pains as any other software company would with cross product vertical integrations and integrations in general... (Apple Car Play Ultra might solve this..) it could also be that they are not hiring the best available talent here since it's taken by the magnificent 7 companies.

Of course not. The issue is that it's not "the firmware update". It's 30+ separate firmware updates all connected across a serial data bus. Car companies still build cars as cars, with different teams responsible for different subsystems and not one software team for all parts. The infotainment system is fully capable of OTA updates at both an app and OS level. It's just an Android system. But that's just one of dozens of dependencies. The headlights have software controllers that take input from light sensors and steering position and suspension loading sensors and connect to switches in the body control module that are represented in the PCM and reported to the mobile app through the LTE antenna. It adds up fast.

Tesla and Rivian have earned the "laptop on wheels" moniker both as an insult and as a compliment in how they have integrated their hardware network.

The infotainment's flash storage is not where all the software lives. Most control modules do have a failsafe system in protected memory. But most do not have three copies for the update, the last version, and the failsafe. So if an update fails, it generates an error code that requires a repair.
