Its probably one of the worst accidents one can suffer.
Even though it is not your fault, one still has the bad image of that pedestrian.
Happened to me 6 years ago. Hit a drunk pedestrian that ran into the road. I had no way of avoiding him. Managed to swerve a little, resulting in him runnign into the fender, hitting the fender and mirror with his body, the windscreen with his shoulder and bending the roof lining with his skull.
Managed to save my Sabre. Car was out of the panelshop and the guy was still non responsive in ICU. Doubt he made it, I chose not to call again and know. Took me a while not to get upset with people walking dangerously into the road.
