The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.
So does each language have a fun mnemonic?

It doesn’t matter where you hold the wheel. When you’re turning right, you’re always doing the right movement for tightening a screw, no matter the hand position. That’s the point.
A clockwise rotation turns a car to the right (in forward gear) and tightens a nut (right hand threaded). But this is not a rotation to the right. It’s a clockwise rotation. You can’t rotate “to the right”. That’s the point.
