You literally said:
That directly implies that it didn’t address any issues you cared about, and I listed many it did address that you had mentioned.

was something radically wrong. That’s why they chose to take the radical step of rewriting it, along with switching out much of the exec team and hiring new software leads and engineers. That’s literally what happened.
It’s precisely the same choice I would have made, and I say this as a former founder and CTO.
Technology has progressed and now we know how to make antennas small enough that they can even fit inside the phone, or inside the car.
But there is more to it. Actually, older phones with extruding antennas had better performing antennas. But the density of cells (towers) has increased greatly. Since now you are much closer to the tower, your phone (and car) can use less power and allows for a less efficient (but again, much lower power) antenna. Modern phones (and cars) support a wide range of frequency bands. To handle this and to cope with the detuning effect of the hand or the head or the glass, they include multiple antennas. Some antennas can even be tuned electronically on-the-fly to compensate for these effects.
All of which is to say: there is very little issue with the cellular reception in the vehicle. The cutouts that people complain about (including me, preciously) are likely the result of concurrency issues and buffering issues, and not network connectivity.
Furthermore, there was never an antenna on the roof, and Sirius/XM was never promised.
Sorry, but whether you find it hard to believe bears no relevance to the facts. Apple, at present, is the hold up. This is not uncommon or even bad; this happens for apps one releases to the App Store just as much as CarPlay review. There are countless complaints about it from developers, regularly.
The upside of the “walled garden” of Apple is that everything that eventually gets released passes muster and is generally solid all around, with much less spam compared to, say, the Google Play Store.
The downside? It can take a long time to get things approved.
And I wish I had a unicorn!
But we have to be realistic with our expectations, and remember that perfect is the enemy of progress. The latest software is a massive, Herculean improvement, and it’s important to remember that Rome wasn’t built in a day.
