Software updates have, more than once, changed my settings for things like autopilot without warning, and I’ve only discovered it when driving and turning autopilot on.
I feel like this point can’t be overstated enough. When I need to go somewhere, I shouldn’t need to reorient myself because the car receives software updates all the time. A device that’s constantly changing is inherently unreliable, even if technically it’s improving over time.
If people didn’t do this it would happen faster. Not everyone has the luxury of immediately switching, just like the “move to another state” argument
