evidence: People required faster machine horses which consume inexpensive and clean fuel, whereas horses need good food for muscular energy and strength to drive a cart which is quite expensive. Natural fuels used to run vehicles give no residue except smoke, while a single horse produces tons of manure in a year which had to be clear completely. Cars did not take rest and work continuously for long hours but horses demanded rest at a particular interval for maintenance of their health and muscular strength. Cars didn’t need any special driver to drive it but for horses, special coachmen were hired who were experts on riding the horse. The horse cart was an extra financial burden on the owner of the horse. Cars are made up of the material which is metallic steel and lasts long, while horse carts were made of wood which needed to be regularly repaired or changed in four-five years. The horse has limited life to work and need veterinarians for their regular health check-ups but cars had a long life to work continuously and need little maintenance.
