Honestly, I've only ever repeatedly dismissed an update once -- the dark period just before FSD Beta went public - I was frustrated by meaningless updates that kept breaking things like USB media album art, decreasing AP quality, etc. During FSD Beta, I've also never had an update just force itself on me. IMHO there has only once been a "known safety problem" (discounting nonsense NHTSA freakouts about seatbelt chime edge-cases, among others): the release of FSD Beta 10.3 which contained a bug that, under certain conditions (Sentry+Park), left the FSD computer in low-power mode while driving, and thus caused horrendous FCW and emergency braking false alarms. In that case, EVEN THEN, the immediate (overnight, from the night it was released) fix was to roll back to the latest non-FSD release version, so as not to corrupt profile/system info of the base firmware version. That was a clever fix - and it was patched/re-released as 10.3.1 just a day later I think.edit: @FalconFour What about software updates that fix a "recall" notice? I don't know if one could dismiss an install that was issued in order to fix some known safety problem.
But at no point was it ever forced. Some people held onto the buggy version, knowing it had the issues (and how to resolve them), not knowing when Tesla would come up with a re-release to get FSD back again. Unfortunately, I was one that applied the update (downgrade) as soon as it appeared without checking the version. haha. But... if you don't tap the update, you don't get the update.
The fundamental point being, updates take a while... and it could be a much bigger safety issue if an update forced itself at the wrong time, preventing you from driving the car. The owner/driver must always be aware of, and choose when to, install an update and disable the car for a number of minutes.
