Look at the length of the cable, it is way... to long, that thing will get caught in the rotor and cause a major malfunction. One of the first things I learned about mechanical disc brakes when they first came out was to cut the cable about 1 " from the pinch bolt. And that is one of the first thing I teach a new mechanic when I train them. I doubt a shop did that.
No! Thats Adam from 'Bikeforums-net', he gives a very sensible and understandable explanation as to why he had to find the dummy a new home. Just overly cumbersome for apartment living in NYC and in the end didnt add utility above the experience and needs that were filled with his trekking bike w/ attached trailer. Might have worked if he lived in a sprawling 'burb and owned his own single-family home with space enough to both store and manuver the rig.
Adams a very nice and sensible dude, admittedly I dont know the wife...lol
