New cars ARE great. I went from half screen Android Auto to full screen when it was released. It's a 30 second update. I know, the end of the world shit.
Buy a 90s shit bucket if you don't want a nice infotainment, I guess. Modern software needs updates. I've never sat more than a few seconds. They are rare updates, I've got 3 in 3 years.
Nothing inherent about modern software makes it require updates. You only need to update software regularly if it has external connectivity so you can patch vulnerabilities, and forcing that on people is just an excuse to force "feature" updates that include lots of bloat and spyware. It should be illegal to make connectivity mandatory.
