A new survey of Washington's Capital Bikeshare, done for Capital Bikeshare, says four in ten users report using cars less -- for an average savings of 523 miles for those users.
The survey's authors say that translates to a total of 5 million miles not driven.
But the survey also found that bike share users tend to be, "on average, considerably younger, more likely to be male and Caucasian, highly educated, and slightly less affluent" than the adult population of the Washington, DC area.
And even though the survey found most (56%) of trips were for non-work purposes, more than nine in ten bike share users are employed, compared to just seven in ten adults in the Washington region.
* 64 percent said they would not have made the trip without bike share;
* 15 percent said they joined bike share because of a "Living Social" offer;
* More than half of respondents used bike share as a feeder to reach transit stops.
