> Automakers didn't update the cassette decks in their cars when CDs came out.

And reasonably enough: few people even in the early 90s had CD changers in cars, and people didn't want to scratch their discs, and in any case everyone pretty much still had a tape deck at home - it wasn't too hard to copy your CD to tape, which was cheap, small, rerecordable, and more durable, and sound quality in cars wasn't great anyway.
