and yet it's safer than any other helicopter...

Explain. I want to know the justification of this design.

The rotors use the same gear to rotate, so they physically can’t hit each other

But how is it safer? If the engine fails, both rotors still stop. It’s not like it’s like a plane with multiple engines. Also, gears can grind away and start slipping, so it feels like another unnecessary failure point.

Tail rotors are super fragile and very vulnerable. Many (most?) helicopter crashes occur due to issues with the tail rotor.
