On lightly traveled roads, the main thing that car speed affects is reaction distance. So your job as a cyclist is to make sure that drivers see you at the soonest possible time. That means wearing bright, solid colors that contrast with road, sky, grass and trees; wearing a light or lights and plenty of reflective gear in low light conditions; and NOT "hugging the white line." Stay far enough into the traffic lane that drivers behind you will be able to see you. Use a rear view mirror.
On narrow rural roads, it is appropriate to ease toward the right side once you're sure that there's no oncoming traffic in the opposite direction and it's safe for the traffic behind you to pass. But it's really important to stay visible.
You might want to see if there are club rides in your area that you can join - I do believe there's safety in numbers.
And 20-22 mph is a VERY respectable average speed in hilly terrain. You might think about joining a racing club!
