Agree totally. It has to be so simple as to be invisible, even though that is suboptimal. Yup, it would be better if Gran cared enough to understand. She doesn't. (And yes, I believe that Gran *could* understand, and what's missing is desire, not ability. Obviously, better metaphors are great, if she cared.)

Also -- the way that you make the safety systems work in crypto for Gran is the same way you make the airbags work for Gran. They just do.
