He wants to stop riding because he can't stop thinking about the crash? Sheesh.
I ride motorcycles and I run everyday. I run through intersections with green lights quite often, as I hate stopping in the middle of a run. You have to be very diligent checking in all directions before you cross, and if something happens, well you assume the risk when you do that.
I recently got "pulled over" for running through an intersection. The cop rolled up next to me and told me that he didn't want to be scraping me up off the street.
The only crimes committed here, was the runners lack of awareness, and that dude is riding a scooter.
