Great video, Steve, thanks for posting. This was the epitome of non-automotive transportation. London was the largest and wealthiest city in the world at the time, and was functioning very well without cars.
People on this forum will be quick to say that the cities were choking on horse manure, but that is nowhere evident in this video (mainly because it isn't true!) People here will also talk about how horrible living conditions were at the time. Maybe so, but that had absolutely nothing to do with the absence of cars. The people in this video look reasonably clean and happy, and they're noticeably fitter and peppier than their modern counterparts.
