>Having had a front-row seat to the data, what's your take? Do you think Tesla's Autosteer helps, hinders, or keep accident rates unchanged?
From my subjective view point of the data - Tesla's autosteer overall helps to reduce accidents. But only when the operator is fully aware of the systems functions and alerts.
Driver assistance systems are wonderful technology and should be standardized like seatbelts, airbags and ABS are. The underlying issue is related to its slow adoption and use, and not a lack of functionality. How the alerts and information of impending caution/take-over required/accidents are presented to the driver is the main hurdle to its lack of wide spread adoption.
Tesla autosteer has a "Delightfully Counter-Intuitive" (as Musk might say) manner in which drivers are taught to learn how this system functions and what its abilities and limits are, therefore reducing the accident rates - in my naive (data) opinion.
Main point being, driver assistance systems could help reduce accident rates....as long as drivers know how to use them, how they function, and what all their literal bells and whistles mean, to the point where you're always supervising the system (whether you realize it or not).
