Has London ever had any bus routes whose outer terminal operates on the
basis of a "loop" say round a big housing scheme perhaps with some
journeys going clockwise and others anticlockwise round the loop? I
suspect not because such "frying-pan" shaped routes don't tend to lend
themselves to having sufficient layover time to recover from
London-type congestion delays. Maybe some of the services which don't
venture into Central London run on this basis?
