Others have made better points but I want to add another thing to point out you can also be making the same "is-ought" mistake yourself: Impaired drivers (drink, drugs, sleep), bad drivers, dangerous drivers, etc. who ought to use the self-driving function are exactly the kinds of people who won't and continue to drive badly. What this means is the safer drivers leave it off (because they outperform the system), while dangerous drivers also leave it off because they mistakenly believe they outperform the system. The traits that it's meant to protect people from are the very traits that ensure it can't do its job.
