Even humans have difficulty dealing with weird cases. Car accidents happen for many reasons, including the driver being unable to process the incoming information in the given time.

One of my pet peeves is the lack of raised markings (Botts' dots or other types) on highways. With the right combination of wet streets and lighting, all of the lines on a roadway can seem to disappear. A machine with different sensors may actually be able to detect the lines better than a human could in this particular situation.
