In this instance it's very likely that when the driver looked for oncoming vehicles (and saw a car traveling at road legal speeds) the biker wasn't there. In that case the statement "I never saw him" was possibly incorrect, and should be modified to read "When I checked for oncoming traffic the biker was not there." Had the biker been driving at road legal speed, he would still not be there when the diver made his turn.
In any event, another motorcyclist has died. That doesn't surprise me, it just makes me glad that I'm no longer one of them. If there's a chance that I'm going to be involved in a fatal accident with a motorbike, I'm glad I'm the one driving sensibly in a car...
