I was thinking (before I even knew this couple died) that riding a bike is inherently a dangerous activity. And possibly reducing time on the road and walking more? Yesterday I was cycling in and around Central Park and NYC's Westside and there were enough mini-happenings to get me to think that it's too much. In a one hour span I had - two cars cut me off. Numerous people squirting in between cars to jaywalk 5-6. Cars that run right up your @$$ and try to move you over to the side and folks too busy to cross on a yellow light to even notice a bike might be approaching. Last bit is some wanker wearing a ermine coat walking directly in the bike path with his arms swinging as if he owns the lane.
I feel bad for the couple as they had more stories to create and tell. Not right, but I've seen enough of these stories over the years to know you take your hands into your own life on a % basis.
