   I had a look at the plugin - it does find some interesting things.  I 
find that truckers use the Scout App, and the profile where they drive 
around a huge factory to pick up / drop off a load appears the same as 
if a car is going through a previously unknown subdivision.

   So once the plugin identifies an area of interest, confirm with 
imagery or TIGER for the next step
    - add driveways to a factory
    - Add new road(s) from TIGER
    - Schedule the area for a survey


   The odd cloud of points comes from random inaccuracies of a 
smartphone inside a vehicle, and excluded for a certain distance from 
existing roads to minimize false positives.
