I read the papers in the OP and the paper someone linked for you (you're the lazy one, not everyone else) and I still agree with the OP. I suspect you didn't read the papers in the OP because you're not talking about the same things the OP is. The raising the speed limit example is completely irrelevant to the OP's point - we should make certain urban roads narrower because that makes them more friendly to pedestrians and cyclists without making them more dangerous. You can bitch all you want but until you start discussing the article in a reasonable way you're going to get downvoted. Perhaps if HN pisses you off so much you should find a different community to participate in?
