I'm not sure car shares can explain this, because Cambridge (and other cities that use car share a lot) are not unique in this problem. Out of curiosity I pulled out B08141 2011-2013 (Means of Transportation to Work by Vehicles Available) by place. I looked at the percent of all workers who drove alone but who said they have no car. Range 0%-6.8% Median 0.92% Mean 1% Cambridge 1% Boston 1.6% Here are the top 5 with this anomaly. I don't know anything about car share availability in these areas. It would be interesting to see if there is a relationship.

Possibly these people use such a service to commute.

An issue that has come up is that we are seeing a small but noticeable proportion of commuters who state they have 0 vehicles available but whose primary commute mode is driving alone. Aside from the obvious explanation of making a mistake when completing the ACS survey can anyone provide thoughts on how we might explain this anomaly?
