Yes I have been hit by a car, yes I walked away, but my right kneecap was dislocated and got a lot of nerve damage in my right leg. As a result I no longer have feeling from about 8 inches above my kneecap into my mid shin, mostly on the inner side.

My bike was mostly fine because the car merged into me on a road, but when I fell the top tube dented in around my right knee.
