When horses were the main way of getting about the amount of **** in cities was obscene and they were smaller then and only the rich really used them. The only way horses work is in small rural communities and even there they chew up the paths PDQ. I suspect that with the amount of food they eat plus emissions they're probably worse than a diesel engine. You can always wind the windows down.
