As gas prices rise, so does slugging

Slugging, also known as "casual carpooling", is a self organizing form of carpooling where strangers pick up strangers for the commute to work. It's spreading in major US cities. I suspect it is illegal in the UAE.

Here's an article about its spread. Here's the slug-lines.com website. This is an old favorite about slugging.
