Title: It’s not that easy!
Horses have a mind of their own, and sometimes they disagree with the driver. In such cases a lot of tact is needed to keep the train on the rails, so to speak. if the driver goes recklessly against the horses, the outcome is often disastrous. Not all coaches reach the end of the tour intact. I have used here BW in order to show how well this fits the atmosphere of the picture and even enhances it.
