Well then the warnings were there people just ignored them. So sorry to hear of the young child that perished. I'm sure he just wanted to be with Dad and was happiest when he was. Hope the family takes solace in that.
Drivers we need to take a second each trip and evaluate our driving habits, I see drivers every day in a big hurry tailgaiting, improper lane changes etc... as well as you do too.
I am constantly cajoling, preaching, scorning, the "professional" drivers that I see doing these things, and usually end up getting told to "you drive yours and I'll drive mine", or something to that effect.
This is a tragic example of what happens when we fail to take the extra effect to insure everyones safety.
