Horses were , for the most part, replaced by cars. I know because my school books said so
Horses just weren't the only thing that was replaced by cars.
150 years ago, most people travelled by foot. And most of those journeys have been replaced, and extended by car journeys.
Houses built pre-car, espeically in working class areas were built for people whose primary form of transport was walking, and maybe the occasional cab (horse & buggy, of course). Bicycles became popular because they were a quick efficient way to get places, compared to walking, and relatively affordable, once they were around in large numbers. Cars became popular because they were a quick, efficient way to get places, compared to cycling or walking. And they became relatively affordable as standard of living improved and cars became ubiquitous.
Now, many people live in areas designed for people who walked everywhere, but they own cars with no place to park them.
Now that's settled
can we stop bickering about semantics?
