Maybe I'm alone on this, but is transport only an economic matter? I am not a package, a cardboard box. I have senses and a brain which processes to some degree, and as a result I need to be transported with more consideration than a parcel. I find the London underground to have crossed the threshold from acceptable human transport. Infinite shoe-horning is not a solution. I'm aware of the various problems that need to be considered, but I think my psyche should not be excluded from consideration.
