If by one lane roads you mean one lane in each direction, it's the same. In this case the driver will have to slow down behind you if the oncoming lane is occupied.

Even texters have to come up for air every few seconds. When they do they will see you as relevant to their line of travel and take more care, probably stop texting until they pass. Wear bright colors and use a mirror.

Honestly, being clipped by a motorist who thinks they can "squeeze by" when there is not really enough room is more likely than one running into a rider who is clearly in their path.
