Tip: Road Rage prevention. Don’t take guff from drivers.
If there’s no fog line, watch for approaching cars, and then signal them to pass when it’s safe. Usually works.
If he won't pass, use your camera phone or camera. Keep it handy and watch that rear view mirror. When the car starts slowing, pull out the camera and start aiming (practice that). Usually that is enough signal to the driver to keep moving. To be sure, take a side view snapshot, and of course the license plate.
If he’s stupid enough to try something, you’ve got proof. In the old days, we just caught up with them at a light, kicked in the driver's door and took off.
