I'm very aware of that. Sometimes the timetable shows what is called a "guaranteed connection". This, in fact, means that it is the same vehicle making a through journey. It's all to do with the UK regulations relating to the registration of local bus services and their eligibility for Bus Service Operators Grant, plus the need to tie in with drivers' hours rules (which means that, sometimes, drivers' movements have to be different from vehicle movements).
Do the drivers know that you are also an expert on their movements...........?
Not sure about easy. Walk to Jarvis Brook from Rotherfield gonna take 20 mins on a busy road, wait for an hourly train to Uckfield, then a slow bus to Lewes & a train to Falmer. Think driving to Lewes is a lot easier especially to avoid a shit return journey & walking back up a nice hill to Rotherfield, on a busy road in the dark. Am I wrong?
