Been on many of routes myself where the bus behind has ended up catching up and 'leapfrogging' the late runner that has been getting rammed with passengers and personally if I know that a bus is running way later than it should, I just wait for the next one as it'll be a heck of a lot quieter and quicker too!
Stagecoach's 16 and 23 in Sunderland are the same, mostly run in 2's at peak times.
