You make my point for me Neil. The bus lanes should be removed.

Only if there is enough room on the road to run an effective bus
service. In Central London, there usually is not.

In any case, if there is no room to overtake safely, then no overtaking
should occur. I cannot see any incompatability issue here.

Depends on your view of incompatible. Putting modes together with no
overtaking just results in everyone moving at the slowest possible
speed. Thus, it makes sense to either segregate, or ensure there is
space for overtaking[1], in order to gain maximum throughput from the
road.

[1] One way systems are a way to provide for this if the roads aren't
wide enough but there are sufficient of them.
