One of my first jobs was working on DAB digital radios. Our workhorse low-end model was quite flaky, but it had a watchdog timer that would reboot it if it hung; and it was so simple that it would get back to acquiring a signal in a fraction of a second. So the upshot was, a system crash just meant the audio would cut out for maybe 6 seconds, then start playing again. For the user, completely indistinguishable from poor radio reception, which is always going to happen from time to time anyway. Crashing wasn’t a problem at all as long as it was rare enough. (I like making robust software and hate crashes, so I don’t like that approach, but I use that experience to remind myself that sometimes worse really is better, or at least good enough.)
