1.0 security. Belts and safety nets. In the meantime car technology has progressed to such an extent that optimum safety for passengers and bystanders is guaranteed.
That is why there are now no more road deaths. However? The fact that the number of road fatalities is on the rise again and that we even have the first death by a self-steering (Safe!) Vehicle, does not even do anything impressive in the statistics in terms of accidents per driven kilometers, according to Tesla. A real reassurance.
But seat belts, wrinkle zones and ABS are fantastic inventions that have saved a lot of lives in the meantime. Yet it is not the case that 'Safe Driving was invented by Mercedes, Saab and Volvo'. Because in the field of safety, everything has been tried before. And with those self-driving electric cars, it will probably be all right too. But we hope not to experience that again.
But that landing net for pedestrians? We don't see that coming back.
