Blimey, @oakleaffy , that carriage driving chaos is quite something.
You know, for all that the modern, car-filled city seems potentially unfriendly to horses, I've read a lot of historic newspaper accounts of bolts in horse-filled days of yore. If you think banging off a shatterproof bus windscreen is bad, consider for a moment what used to happen when a bolting carriage horse met another carriage's shaft – or bystander horse was run into by bolter's carriage shaft. It was exactly as horrific as you'd imagine.
Then there were all the lovely spiked railings, non-safety glass shop windows, areas in front of sunken basements...
The accounts are shocking to read.
Strange to say, I think the modern city may actually have been safer for these bolters.
