Why do you suppose that is? We can get 15 messages a day about being safe, staying focused, the last stop is the most important, crashes other drivers have in other parts of the district that have nothing to do with my day, and whatever other stupid S* they send out but they can't tell people about this.
Why is the feeder driver killed in a wreck, or the tug drivers killed by recklessness, or the driver who was taken hostage and killed on his first day after being released by his FTO not spoken of? They don't even talk about dog bites anymore.
