Slugging is a self-organized carpooling system that’s popular in Washington DC. People who want to use the HOV lanes troll known meetup locations for folks heading to the same exits on the freeway out of DC, and pick up several strangers. Seems like a great consequence of having HOV lanes… But then I saw the distances and times involved. Alone, people are driving 6 miles, and it takes an hour. In the HOV lane, it’s cut to a mere 30 minutes. With any kind of semi-reasonable infrastructure, bikes would beat even the carpoolers in a race.
