A lot of ink has been spilled on what autonomous vehicles could mean for America, especially if the tech-industry fantasy of a 100% driverless future somehow comes true. But my guest today argues that policymakers need to dig a lot deeper if they want to anticipate the potential side effects of the AV revolution — especially when it comes to public health and equity.

In his new paper, "Equity issues ssociated with the widespread implementation of autonomous vehicles," Dr. Andrew Dannenberg of the University of Washington runs down all the questions communities should be asking before they let robocars run wild. Questions like: How expensive will it be to retrofit our roads so AVs will be able to read them, and will the money come from other modes? How will people with disabilities really be impacted by the rise of "driverless" cars — and the loss of human paratransit drivers to help them get around? And maybe most importantly, what community problems will this technology actually solve that couldn't be solved in other ways?
