I think it's funny because even if cars weren't invented then the images presented would still be the same. Cars followed the convention that was before them... horses, and horses with carts and cartridges.
Not really, cars are faster and more deadly. People had to be somewhat careful. The auto industry invented a slur (jaywalking) to convince people the street was no a place for people outside of a car. Look up old footage of cities, people are everywhere in the street.
You and I have seen very different imagery then. I have not seen an image as you have described, yet I have seen many images of what I described. No bias in the search either "roads before cars existed". Obviously I've just done it now to check if I was wrong.
Congratulations, you found three pictures of the two largest cities in Europe and the US at their time. Where there streets with mostly horse carriages? Yes. Where they the norm? No.
Why and when do you think traffic lights and zebra were invented. Why didn't they exist before?
