Opinion: not very useful.
Rural people drive farther to work or shop, that doesn’t mean they interact with more people. I may drive 50 miles to drop off radios for my tech to install but not interact with a single person. I saw one analysis that blamed it on Walmart for driving all the local stores out of business so people in some areas have to drive 20 miles to buy groceries or buy supplies. But again, what matters is probably how crowded that Walmart is and whether you practice distancing while shopping, not how far you drive to get there. I imagine anonymized cellphone geolocation data is available for this purpose, either from what celltowers you are near, or browser and app data.

They're using travel distance to determine who's good and who's bad. Is their data worth a shit? You could put 10k phones into 10k cars and drive them in circles all day and your reported metric would be through the roof, yet there was nearly zero additional risk because people were separated. How are they collecting this data? On whose behalf? With what permission? The only useful data would perhaps be in detecting the change in number of visible Bluetooth devices from January to now. ----- Mike Hammett <http://www.ics-il.com/> Intelligent Computing Solutions <https://www.facebook.com/ICSIL> <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> <https://www.linkedin.com/company/intelligent-computing-solutions> <https://twitter.com/ICSIL> <http://www.midwest-ix.com/> Midwest Internet Exchange <https://www.facebook.com/mdwestix> <https://www.linkedin.com/company/midwest-internet-exchange> <https://twitter.com/mdwestix> <http://www.thebrotherswisp.com/> The Brothers WISP <https://www.facebook.com/thebrotherswisp> <https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg>
