> This is anecdotal, but I've asked about twenty or so UPS drivers that I've met over the years whether they avoid turning left or not, and they all just laugh and say "No, that's dumb." Either they're messing with me, they just aren't following "the rules", this "UPS drivers don't turn left" thing is urban legend. This article is more about the way routes are planned than the individual choices drivers make along those routes. There isn't a lot of room for agency in route choosing, drivers are given a stack of packages and deliver them in the way the route is built.
