My name's Frank Langfitt and I'm a business correspondent. I did this story a few weeks ago. It's about a phenomenon in Northern Virginia called slugging. The video explains it, but it's essentially an ad-hoc ride-share system that developed during the oil shocks of the 1970s. With gas prices continuing to go up, "slugs" say more people are lining up for rides these days to save money.
What struck me most about this is how a symbiotic relationship has developed on its own. Drivers benefit by picking up riders which allow them to zip along the HOV 3 lane, riders save time and money.
There seems to be little concern about safety. Slugs told me one reason is that they come from a similiar socio-economic group: government, office workers and military, so there's some affinity and natural trust.
As to shooting this, I struggled shooting inside the car and getting the light right and i was still learning how to operate the audio controls on the Sony HD camera — hence the changing sound quality from scene to scene). All in all, though, it was fun to ride up I-95 and get a sense of how this phenomenon works.
