Slugging: a sustainable response to higher fuel costs?

...Public transit never shows. But, eventually, a blue Chrysler Town & Country does. The woman behind the wheel rolls down her window and yells a kind of call-and-response.
“Horner Road?”
“Horner Road?” repeats the first woman in line.
“Horner Road!”
And two women get in the van, heading, presumably, for Horner Road...

...

People here have created their own transit system using their private cars. On 13 other corners, in Arlington and the District of Columbia, more strangers — Oliphant estimates about 10,000 of them every day — are doing the same thing: “slugging.”...

A (long - and I have not read it all) post about how commuter behaviour has altered in the US in response to high occupancy lanes - a self organising system for sharing transport - that appears to benefit all. (Click here for the full document)

Yesterday I tweeted about the system that Devon has in place to help people organise car sharing (see below) - and why more councils should be copying this approach. 

But perhaps what is needed is the space to create slugging in this country... So come on local government - can you create conditions in which this might happen in this country too?
