Dear God.
I haven't words to describe what a load of horse chit this is.
One of the responders of course, observed EXACTLY THAT - the adoption of the Model T incredibly improved the streets which were TEEMING with horse and mule chit, and as cities and industry grew - became worse every year.
To hear this, it was so horrible to ride in or so unsafe, you'd be lucky to SURVIVE a ride in one, because they apparently exploded or had some other deadly behavior. Comparisons to modern cars are ridiculous - compare them to the existing alternatives for the every day person.
The Model T wasn't just immensely popular in America - it became a global hit.
For the first time I can ascertain, a man became immensely wealthy because he figured out how to bring a heretofore extremely expensive thing and make it cheap enough for everyone to own - everything from barebones auto to assembly lines and buying on credit.
