I thought I had sidewalk rage, but apparently it's nothing compared to what some people feel...

For the cool-headed, sidewalk rage may seem incomprehensible. After all, it seems simple enough to just go around the slow individual. Why then are some people, even those who greet other obstacles with equanimity, so infuriated by unhurried fellow pedestrians?

How one interprets the situation is key, researchers say. Ragers tend to have a strong sense of how other people should behave. Their code: Slower people keep to the right. Step aside to take a picture. And the left side of an escalator should be, of course, kept free for anyone wanting to walk up.

I get annoyed when I can't get around people... strollers... pairs taking up the entire sidewalk.
