From the article: "A woman bicycling with her grandson on Marcola Road was struck and killed by a pickup truck Sunday as she was repairing her bicycle on the shoulder of the roadway
" (my emphasis).
People in a car will stare at an object and steer right into it. Strange but true.
Usually, this happens to drunk drivers who drive into the back of cars stopped at the side of the road (often police cars) because they cannot effectively perceive the difference between a moving and stopped car. They think they're just following the car in front of them.
This case seems to be different. I believe this is a classic case of "inadvertent drift". Drivers inadvertently drift into shoulders (and bike lanes) more often than many of us would like to admit. Most of the time, there is no one there, so it really doesn't matter. In this case, it did. Tragically. My heart goes out to the family.
Whether stopped or riding, beware of the susceptibility of shoulders and bike lanes to inadvertent drift. When stopping, it's best to get off the road entirely. When riding, I believe the key is getting the approaching driver's attention by riding closer to the center of the lane, and moving over to facilitate their passing only after you have their attention. A mirror is very helpful for this. [NOTE: this technique and it's alleged efficacy is not "standard" vehicular cycling; it is mostly my own opinion, loosely based on the concepts of "primary riding position" in John Franklin's wonderful book, "Cyclecraft". Take it with a grain of salt, but it works for me].
