I beg to differ. No matter how well you educate the drivers, there will be moments of stupidity, carelessnes, bad luck, unexpected road conditions, drunk driving, mechanical failures, somebody else loosing controls coming towards you etc. etc. There is a fair amount of historical evidence to proove that relying on drill and discipline alone is bound to produce mishaps. To err is human, so there is a good reason to add safety devices and warning systems to a good driver education. Where I live, in spite of increased traffic the number of deaths and severe injuries are mostly the same over the last years, or going slightly down. In my view, the reason is multifactorial: better driving education AND better roads AND satefy devices. There is no point in discarding any of these factors. Of course safety devices should have a proven (if possible) efect, good shelf life, and pollution from production should be a minimum, but that is a challenge for the manufacturer. And there is a balance between personal freedom and what could be potentially dangerous for yourself, people around you and finally the society as such. So some things are mandatory, as a motorcycle helmet, safety belt and a 3rd stopping light. Anybody objecting to that? Some are useful or even recommended, as ABS, reversing camera, parking sensors or the like.Why discard that? And the liittle buzzer reminding you of the safety belt is actually a good idea. I might forget someday. I am human.
