Also, maybe this is worth mentioning. Monocab ain't a profit oriented company (yet). It is a project by the Technical University Ostwestfalen-Lippe in cooperation with some other universities.

I can see why people are sceptical - but really this is a proof of concept. maybe it'll turn out a flop - maybe it'll work great. I am willing to see where they take it.

Well, keep in mind we're talking about long single tracks spanning many villages and towns - in places where there is not a ton of demand. The train would: 1. Rarely be there in the moment somebody actually needs it 2. Almost always be empty.

Notice I said the monocab ain't meant as "mass" transport. You wont see 30 monocab back on back all the time - you'll see one, maybe, every half an hour or so - but they'll be there when somebody needs them - not uselessly when nobody cares.

These are much more, as somebody else already pointed out in the videos comments, I believe, indented to replace call busses - instead of having to call a bus and wait half an hour or more, you can just hop into a mobocab which is on standby and get moving.

Living not too far away from the place where the Moncocab is being developed and tested, I've actually had the chance to see them in person and actually sit in one (They are much more spacious than Adam makes them seem)

This system is not intended for mass transport. It is intended for rural places, connections between villages and small towns. A connection between bigger cities with these obviously makes no sense - for villages however these could be absolutely great.
