On the other hand: calling something “Full Self-Driving”, when it is in fact definitely not fully self-driving, kind of flies in the face of the obvious plain text reading of the phrase “Full Self-Driving”.
Decades of experience has repeatedly taught that people are not perfect robots that always read manuals, and if you design your system under the assumption that they are then it is you that is at fault, not them.
There's a reason we have safety interlocks and dead man switches and seat belts and helmets and ... It's no use having a manual that says "do not open the microwave door while it is running".
That’s exactly how the manual/pilot operating handbook and supplements for most airplane autopilots (and airplanes) read.
There's the classic aphorism about tools like lathes: "This machine has no brain, please use your own." But that's usually in an industrial setting with OSHA, mandated safety trainings, inspections, a culture of reporting unsafe practices without judgement, etc.
As CNC machines get cheaper and smaller, we are starting to see things like laser cutters sold to consumers with a pair of glasses and a manual rather than an enclosure. Hope you remember to lock the door if you have kids or pets...
It is a worrying trend which seems to be accelerating in the US due to crumbling and senescent regulatory institutions.
A much better solution is to add a physical safety interlock which prevents you from starting the lathe without removing the chuck key, which is exactly what some lathes do!
I agree the safety level of a lot of Chinese machines is very poor.
Also, aren't chainsaws nowadays designed so that if the user doesn't have two hands on the chainsaw grabbing the triggers, the chainsaw automatically cuts off? IIRC that's a thing.
Edit:there's the grip-safety ("safety throttle") for the trigger finger and there's the chain break for the forward hand, which will push forward and activate the brakes if the hand let's go or if recoil pulls the hand forward.
The user also needs training as there's still no way to guard the exposed blade when in use nor to keep it out of proximity of humans.
