DDH, if you can think far ahead enough, instead of staying to the right, safely move out into the lane and show the palm of your hand to the driver behind you. If you see a car coming before they can, like on hills and such, this is the only safe way to to avoid the situation of being passed by two cars at the same time. It has worked for me many times.

I think the drivers generally appreciate that I'm paying attention and would like for them to pass. This way they get to pass on my terms, which is going to be 10 times more safe than the way they might do it.
