Comment Comment by to3m There was an article about people's tendency to soak up additional road space posted on HN fairly recently: http://www.wired.com/2014/06/wuwt-traffic-induced-demand/(You can also see something similar with internet bandwidth. Same principle, I think.)There's a Wikipedia article about the theory that narrower, signage-free roads are safer on aggregate: http://en.wikipedia.org/wiki/Shared_space(I don't know/care if these are useful to you - simply a brain dump, as you asked) parent to3m 12 years ago
