In the U.S. walking has even been criminalized to some extent for those in out groups. For instance, if 4 black teenage boys walk together in an affluent, white neighborhood they can expect police to stop them. Walking is so rare that a small group of people walking together is seen as something out of the ordinary. I think it’s bad for society to be set up this way.
