Surely if theyre late they must be picking up quite a few passengers, and possibily an increased frequency may happen, and possibly later journeys to trial if the 6am-6pm timetables are being successful.
But I do think there is an everpresence issue with relaibility and I think its down to the constant frequency cuts, all the buses which StreetDeckFan mentioned Arriva 6, GNE X30, 49, X21 and 20 except the X21 to my knowledge has had frequency cuts.
I can name several more 2/2A/10s/21/60/56/X45/16/16A granted the 16/16A hasn't had frequency cuts but the reliability of the vehicles are at fault here. Even vehicles which have 12 mins layover at Park Lane like the 60 still regularly get bunched together. 2/2A are awful for bunching up.
