This is what gets me...they chase some guy for not wearing a seatbelt, but tailgaters, lane-weavers, "I-don't'-merge-properly-'cuz-I-can't-pause-my-conversation-on-the-phone-that-is-glued-to-my-ear"-types, and other such dangerous driving habits are ignored.
This is a tragic story, and highlights the idiocy of priorities law enforcement sometimes has (not to discount the fault of the trucker who hit the pickup).
