I clipped a bicyclists back tire once. Flipped him over. He was mostly okay. Probably 95% his fault because he was riding against traffic, on the sidewalk, and ran a red light.

I still felt really bad.

When people come up with reasons why that won't care because logically they'll be in the right if something bad happens. All I can think is either they are sociopath or that they deeply lack life experience.
