Even as gas prices hit historic highs, many Americans aren't driving any less — because so many of their communities are so car-dependent, they don't really have a choice. But what about people who could skip the pump but don't, simply because they're in the habit of driving everywhere they go? On this episode of The Brake, host Kea Wilson sits down with environmental psychology expert Dr. Ian Walker to talk about why conventional strategies to disincentivize driving don't always work, and why even incentivizing other modes can't always tempt people onto buses, trains, bikes and sidewalks. And then we explore what it will really take to shift Americans' deeply-ingrained travel routines — and why every policymaker needs to understand the irrational, emotional, and deeply human reasons we make our travel choices. Give it a listen, and check out Dr. Walker's website and the Twitter thread that inspired the episode here.
