More like a tragedy of stupidity. People (especially truck drivers) don't look down the road. I see it every day. I'll move over for any vehicle on the side of the road as soon as I see them. (Usually within a mile). I still have people try to pass me on the right, oblivious to the car on the side. (Many have pretty lights on top)
The guy that taught me how to drive a truck used to ask me questions like; what color was the car at that intersection? What was the weight limit on that bridge? What was the height of that bridge? All these questions served to help me observe my surroundings. Many times, I'll see trucks go underneath an overpass oblivious to the fact that there are vehicles coming down the on ramp. If you are looking up the road, you will see those vehicles turning down the ramp and look for a spot in the left lane to allow them a spot to enter the highway.
The same goes for accident in front of you. These multi car pile ups are caused by drivers not paying attention and not looking down the road far enough. You can drive 100 miles per hour on ice, as long as you don't need to stop or steer. You should only drive as fast as you can stop.
