Does the link from the bike club tell us enough? He was entering the street from the sidewalk when struck. Did he stop before entering and make sure it was clear, then proceed? Maybe, but I haven't seent hat happen in a long time.
Yesterday while leaving work I was still in the parking lot, and had a Mom and Dad go through a stop sign in the parking lot without even breaking stroke. I was glad I was going parking lot speed, so it was easy to slow down, especially since I started to slow as soon as I saw them. They rode across in front of me like nothing was wrong, with Dad pulling a trailer with two pairs of tiny legs sticking out of the cover.
