A nonsense and deadly potholes

This is a nonsense

The scenario in the above picture is a nonsense.   The scene is a 'T' junction with traffic lights.   Cycles can only pass across this junction (on the on-road cycleway) if they have a green light, and 'we' have red.   When 'our' light is at green crossing traffic, including cyclists, will have a red, and in practice they should not cross this junction.  So why is there a sign to alert the motorist that cyclists are crossing, when they shouldn't be? 

Our roads are in a dreadful state, with our country lanes being the worst, the cyclists is obliged to keep his eyes open for potholes at all times.
