Sorry, but this is the exact wrong conclusion to make from the available data. Partially automated cars have been driven by average people on the public roads since 2006, when the Mercedes S class got active steering and ACC. There is no data that says that these systems, which are available on cars as affordable as e.g. a VW Polo, lead to more crashes. In fact the only data I have seen suggests that they reduce crashes and driver fatigue significantly.
The issue that such a feature is systematically crashing and even killing its users is very specific to Tesla. Tesla's system has had a tendency to run into stationary objects for as long as it has been available to the public. Teslas have a significantly higher rate of causing insurance claims. There are countless videos showing it happening, the two (possibly three) fatalities so far are just the tip of the iceberg. Tesla blamed MobilEye (their previous supplier of camera-based object detection hardware), but it seems fairly evident that Tesla's system has the exact same systemic issue even with their new in-house object detection software.
My opinion as an engineer working on this exact kind of system for one of Tesla's competitors is that Tesla's system just isn't robust enough to be allowed to be used like all other manufacturer's autosteer/ACC systems. IMO that's because their basic approach (doing simple line-following on the lane markings) is super naive. A much more intricate approach needed. One that does some level of reasoning on what is a driving surface and what isn't. This has been known in the automotive industry for over a decade. Sorry to be so absolute, but frankly it's just unnacceptable that Tesla is gambling their customer's lives on such a ridiculously half-baked implementation.
> Lane following assistance without good automatic braking kills.
Correct. It also kills when it lies to the driver about how confident it is in a given situation. Many of the crashes, instances of cars veering off into oncoming lanes etc. we have seen would not have happened, if Tesla would fall back to the driver in sketchy situations. However what it does do instead is not even notfy the driver that the system is hanging on by the barest of threads. This works out fine quite often and makes it seem like the car can detect the lanes successfully even in sketchy situations. Yet once the system (and the driver) runs out of luck, there is absolutely no chance to rectify the situation.
