If you haven’t already read The Tipping Point by Malcom Gladwell, I definitely recommend it.  The Tipping Point is commonly described as “any point when a gradual change quickens and becomes irreversible”.

Some people are wondering if we have reached this point with sustainable transportation because of high gas prices.

That’s the idea discussed in this recent Wall Street Journal Article.

But I don’t think you need to read the article to see what’s going on.  More people that ever are getting on the bus, biking, walking, carpooling, etc. I definitely see this happening in Ann Arbor, where the number of people participating in the Commuter Challenge almost doubled from last year.

I have heard many people remark that they have carpooled, biked, taken the bus, etc. for the first time recently.

So how do you change people’s behavior?  I think gas prices can definitely help.
