That is the case for any vehicle. Bicycle riders who are not able
to ride in a controlled way (loss of control by accident happens to
them as to anyone else and is not considered base for standard
behaviour) should not ride, just as anyone else in traffic. I don't
see any speciality for bicycles. When a driver gets nearer to the
object he spotted he needs to keep sufficient distance, but when
that decision is due his lights will show him all details or his
sight is so limited that he should extremely careful anyway.
