Actually, replacing some cars with horses (though probably not horse-drawn cars) would solve some of the problems caused by cars, especially the damage they do to the environment.

Inside city bounds, small trucks could be replaced by horse-drawn carriages; they'd be clean (clean_er- horses still er, produce waste) and large trucks should never be allowed in the same areas as pedestrians and bicyclists anyway.

I'm not saying that the current pace of life in very big cities could be maintained in this way, but just the reduction in emissions would probably make up for any short-term financial loss.
