I have never heard of a single motor vehicle occupant being even injured from a wayward cyclist running into them.
Oh I'm sure a few have been injured or killed due to having to take evasive action to avoid that cyclist.
Probably, but even if these cases exist, I doubt the numbers add up to a significant problem, even without comparing to the number of motorists injured or killed by having to take evasive action to avoid other motorists.
One time while I was driving in the curb lane, a cyclist coming toward me on the adjacent sidewalk fell off the sidewalk right in front of me. I didn't have time to determine if I could swerve, so I relied on braking. It was adequate. I wasn't upset because there was nothing else I could have done, and I wouldn't have been hurt.
Many years ago while cycling at night, I was making a slow uphill left turn when I caught a glimpse of a shadow about a foot from my face, then felt a tremendous impact. As I lay on the road, I considered what might have happened. It couldn't have been a pedestrian - too severe for that. Not a car, not violent enough. It HAD to have been a cyclist. So I looked over, and laying a few feet from me was another cyclist and his bike. He'd been speeding down the hill, with no lights on. Our heads hit each other. He was not wearing a helmet. (It wouldn't surprise me if he had also been riding with no hands.) Fortunately I was, so my helmet protected both of us.
I jumped up, grabbed his bike and began shouting about police and lawsuits and so forth. I thought I had a concussion until I figured out that my glasses were crooked. We determined neither of us or our bikes were damaged, so I took no further action. Later I had some doubt if my headlight was working, since only recently has industry been able to produce reliable bicycle lights.
However, had this incident involved a car, the outcome would have been grave.
