A person stepping out into the middle of traffic can also cause the same thing as could an animal.
I suppose that one can imagine a set of circumstances where a cyclist sets a chain of events in motion that ends up in a vehicular accident with the cyclist left unscathed. However, I have never ever even heard of a reasonably responsible road cyclist causing an accident and if they did it would probably require temporary insanity. It is such a remote possibility that it is not worth worrying about.
Now, here in central FL, many motorists have a compulsion to pass cyclists at high speeds on blind turns. It is a form of Russian Roulette, central Florida Roulette?. The motorist might claim that the cyclist "caused" the accident but it was his own illegal, irresponsible and stupid behavior that resulted in the accident. I have seen motorists pull this dumb stund hundreds of times and so far they have all been lucky.
