A new study from Brookings. One of those "well, duh" reports, but policymakers who don't realize the obstacles of not having a vehicle because it's completely outside their world view need to hear this shit. The link to the full paper is available from here:

Recent reports quantify the additional money required to own and operate personal vehicles, as compared to the lower cost of traveling on public transit. However, this method of accounting fails to consider the fact that poor workers without a car may not be able to search for or accept a better-paying job because public transit doesn't take them there, causing these workers to lose income or benefits as a result. This report outlines opportunity costs experienced by transit-dependent poor households, and concludes that when all costs are considered along with benefits of private vehicles, it makes sense to press for more assistance and policies that reduce car ownership costs for poor workers."
