I saw them around here somewhere. I haven’t bothered to run them personally, but after ditching my car and WFH, suddenly I can afford to support my wife and child while they both go to school - by way of explaining why I haven’t put the assertion under a microscope.
Couldn’t conjure up the source I got it from though. After some random figures looked up and shitty napkin math, I would only be able to argue for about 22 miles per Mhour for the average American.
