Your reply made me check for the UK, so in 2016 we have
"For teenage and adult cyclists, accidents are more likely to involve collisions with motor vehicles, but about 16% of fatal or serious cyclist accidents reported to the police do not involve a collision with another vehicle, but are caused by the rider losing control of their bicycle." [1]
Not quite 30% but much more than I expected and obviously not negligible. Thanks for the rebuttal.
