Answer:
Invention is the mother of necessity
Explanation:
In the given instance it can be seen that the invention of the automobile necessitated the building of new roads which in turn necessitated invention of traffic's regulations and finally invention of a new organization called the highway patrol.
This illustrates how necessity in a given situation forces people to invent technologies and processes that will tackle the present challenge.
There is no future preplanning of the inventions, but they come as the need arises.
