It is interesting the number of things that sharpen when there is risk on the line. We've already discussed how narrow streets without signs are safer for pedestrians, but its true for a lot of things. The trick is to make it really painful but not fatal.
Do you have a link to the discussion on narrow streets? Sounds ridiculously interesting. At first thought, I can't help but think this is something that doesn't scale. Thought being that it only works because a unique situations puts drivers into alert. Not sure how I could test that, though.
