Imagine that you are driving home through a forest, and you round a curve and notice in the periphery of your vision that a pickup truck is off the pavement on its side. As you briefly consider the possibilities, you decide to pull over. Carefully choosing a spot that is well off the pavement so that you don’t become another casualty, you pull over, stop your car, lock the doors, and jog back to the scene of the accident.
There is no one else around, and you almost chicken out, because you barely remember your CPR training. What will you do if there is carnage? You can’t get a cell signal, so you decide someone has to do something. You jog up the road, trying not to fall down the bank into the river, and arrive at the rear bumper of the truck, which is pointing up toward the trees.
Fortunately, the front end of the vehicle is not attached to the trunk of a tree, or sliding into the river. You crawl around to the passenger side, and someone yells, “I want to get out of here!” A reasonable request, and since the person is not dead or apparently injured, you assist as he climbs up and over the side of the truck.
As you check for signs of head trauma and look for flares, help arrives. You depart from the scene, considering how lucky the driver is to be alive, and how lucky you are not to be the driver, with a bruised leg and a truck in a ditch at the end of the day. You remind yourself to pick up some flares on the weekend.
