I guess the way I think about it is, if person is driving 70mph with ACC enabled and crash into a clearly visible roadway obstruction (firetrucks are highly visible even from a distance), that's totally on the driver who enabled the feature. It's not the job of that feature to prevent that kind of accident. If other statements on this thread are correct, then this Tesla likely did not have autopilot and certainly not FSD- it had a pre-autopilot ACC system which led to a tiff between the vendor and tesla (possibly because tesla was being irresponsible while deploying it). So it's really hard to say this is a case of tesla cars automatic driving being systemically faulty. I do believe that to be the case, even for FSD, but it's entirely speculation.
