Must have been memorable, the very different mystic East. I used to see an old mothballed international flying boat on the slipway in Cowes. Huge for its era.
The sedan may be green and somewhat regal, but a horse drawn trap or cart would seem smoother.
There are still huge numbers of human powered vehicles around the world, pedalled rickshaws etc. I have never felt comfortable or safe in them the few places it was the only option, Calcutta stands out in my memory...
Many now in London, for the tourist they provide on-board music, lights and I assume an almost equally memorable experience...
