I think intentional or not it did pick motors over horses, the established alternative at that time. It may not seem like horses were a viable alternative viewing it through the lens of what we know about todays motor vehicle but at that time the nations economy revolved around the horses ability to move people and goods from one place to another. Breeding, trainning,equipping, buying, selling,veterinarians, blacksmiths, livery stables, it was a huge industry and the only game in town as far as personal transportation until the horseless carriage was invented. 150 years from now people might have a hard time imagining that todays ic motorcar was an established alternative.
