Admit it. When you’re alone in your car with your windows rolled up, you’ve always been pretty selfish. Don’t feel bad, almost all of us are guilty of the same trait. And now we have help. Directed by our mapping software, we’re all taking the optimal routes to get where we’re going. While these software-determined paths are ideal for the individual, they can create more traffic in more places, and end up being being terrible for everyone else. As The Atlantic’s Alexis Madrigal explains: “A new information layer is destroying the nudging infrastructure that traffic planners built into cities. Commuters armed with mobile mapping apps, route-following Lyft and Uber drivers, and software-optimized truckers can all act with a more perfect selfishness.”
