Is the Mercedes-Benz S-Class safe enough for family use?

The Mercedes-Benz S-Class introduces world-first frontal airbags for the rear passengers, integrated into the backs of the front seats.

The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
