What if you were traveling on the Interstate during a rain storm with poor visibility and you noticed an 18-wheeler that was tailgating several cars. It switched from lane to lane and road on the ass of each car. At one point, you were riding alongside this truck and you could tell that there was maybe 1 1/2 car lengths between it and the car in front of it. And all vehicles on the road were going over 60 miles per hour.
Would you call the truck company and report the driver, knowing that his behaviour could easily kill someone one day? Would you chalk up the bad driving to the weather and not make the phone call because no one was injured but the damage to that driver's life (and subsequently, anyone else who depends on him) could be enormous if he were to lose his job?
What would you do?
