Filed under random but fun calculations, Alasdair Rae estimated the number of people within interstate boundaries:
I loaded up a MapTiler streets backdrop layer in QGIS, created polygons from the the US national road network file from the Department of Transportation website (this required a lot of error checking/fixing) and then summed the population of all areas bounded by Interstates – including those in Hawaii, Alaska and Puerto Rico.

This is a fun map by Matt Dzugan. Search for a city, and see the segments of highway in the United States that are headed that way:
I set up thousands of queries to Google Maps, asking for directions from Point A to Point B and parsed its responses, looking for the text toward ___, signs for __, and ramp to ___.
This enabled me to build a database of all the segments of road that are listed as heading towards various cities.
