If you look at the pictures, there is a bend in the road. The driver had very little time to react.
Per the question as to why I have made the conclusions I have, we never used to hear about crashes involving stopped vehicles along the side of the road. Now you seem to here it all the time. What changed?
BTW:I do buy into the idea of the cop blocking the existing problem. But where I have a problem is when the cop takes up excessive space, well beyond the stopped vehicles. There are times when it is not in their best interest to do so. When the extra margin is needed, then do that with a warning car farther back, so traffic has time to respond safely.
I guess I've just seen a lot of very poor situations. One that comes to mind is on a 3 lane road, cop had a car pulled over. The car that was pulled over was way off the road. The cop could have easily blocked his walking area next to the car, and still stayed off the road. Instead the cop blocked half the traffic lane. I was 2 lanes over and was able to observe 2 near misses, from a chain reaction as a result of cars stopping to get around the cop car half blocking the lane. Just seems so illogical to disturb the flow of traffic right at the point you want things to be the most safe.
