You are right! But it is now apparent that the question I had in mind is completely different from the one I actually asked. nbadg caught on to what I meant which was more along the lines of: could suspended cable transportation be a feasible mode of public transportation in cities?

Yes. The biggest benefit is very low ground footprint and highly predictable traffic flow. A few articles discuss it as a reasonable form of mass transit.
