One can hear a car coming from quite a distance. I simply stop peeing if I hear one and turn my back to it. It's good if your bike is right there so you can put a hand on it. I never pee if I would be facing a house. We have a big deal century here. The sponsors do hear about riders peeing on lawns which is not helpful for the ride's continuation. I rode it once . . . too many idiots, though I should say "inexperienced riders", but maybe they are just idiots. Hard to tell sometimes.
