I live in a rural area - the main reason I often do not use public transport is the fact that it runs way too infrequently - and depending on the holidays of a neighboring state may run even less often. As much as I would love to use public transport, over here where I live, it often just doesn't fit. A quick trip somewhere would turn into a 4 hour journey.
Also, as I already commented under another comment, as far as I understood, the monocabs will be on stand-by at every station.(they might've changed that though, in which case I fully agree with you - an app is stupid)
The monopods would essentially all move - Dunno if that'd work well in practice - never said it would - I just think we should judge the idea to be "techbro bullshit" just yet without having it really seen anywhere close to action.
