This is a map I found of California c. 1895.
120 years ago, the automobile was an exotic curiosity, either steam locomotive on wheels or, worse, a miniature, silent battery powered street car on wheels. The y were still rare, expensive, and produced one at a time by tinkerers who should scarcely produce more than five cars a year. Meanwhile, bicycles had recently assumed their modern form of two equal sized, rubber tired, spring-spoked wheels with a chain drive. All of those things were about as old as smart phones are today.
This is the sort of road network that was being built for them in the first era of good roads.
