I recall someone telling me years ago about getting lost on vacation and accidently exiting the freeway in their RV and driving through the San Francisco Financial District at rush hour. He said he was harassed by everyone for 45 minutes until he found his way back on the freeway, worst driving experience of his life. He said even pedestrians were mocking him, everyone cut him off, honked their horns.

And, I've seen what happens when a car foolishly gets in the middle of a critical mass crowd. It's a mistake they won't make twice.

There's a lot of truth in the article, people are attached to their rules and conventions...throw them a curve ball and they'll freak.
