A study of 6,281 hypermilers car sharers by University of California has shown that over 80 percent of those joining a car sharing program dropped their own vehicles when they joined. For those that didn’t manage to ditch their cars all together, the program meant that many no longer required a second car.

The study also confirmed car sharers drove fewer miles and used newer and more efficient cars.

“Car-share households exhibited a dramatic shift toward a carless lifestyle,” the study authors wrote. “The vehicles shed are often older, and the car-sharing fleet is an average of 10 mpg more efficient than the vehicles shed.”

Now if only this was an option for me, I’d quite gladly give up the Volvo for a slice of the car sharing action.
