    Episode 21: The Car Industry + What Our Vehicles Say About Us

    In this episode of Look Both Ways, David & Wes drive straight into the changing car industry and what today’s vehicles reveal about identity, status, and the future of transportation. From cheap Chinese EVs showing up near the U.S. border to the pressure they could place on Detroit, they explore whether companies like BYD and Geely could bring back the affordable car in America and why U.S. automakers may struggle to compete. It’s also a conversation about how transportation has become deeply tied to culture and identity in the United States, why so many people buy vehicles they barely use for their intended purpose, and what all of that could mean for the future adoption of autonomous vehicles.

    BONUS EPISODE: “Freedom to Drive” + Everyone Deserves Sidewalks (Live from Denver)

    Freedom to Drive - In this very special episode of Look Both Ways recorded in front of a live audience on a rooftop in Denver, Jill Locantore of the Denver Streets Partnership joins David & Wes to dig into the Trump Administration’s “Freedom to Drive” initiative and what it says about how we think about congestion, mobility, and who the transportation system is really for. They contrast that national framing with a local story, Denver’s successful “Denver Deserves Sidewalks” campaign, which shifted responsibility for sidewalks from property owners to the city. It’s a conversation about competing visions of freedom, what it actually takes to build better cities, and how policy choices shape everyday experience on our streets. Thanks to everyone that came out for a really fun event!

    Episode 20: Driver Assistance Isn’t Making Us Safer + Shrinking

    Driver Assistance – David & Wes dig into driver assistance systems and the question of whether they’re actually making our roads safer. Following a recent NTSB hearing, they explore both the promise and the problems, from real potential safety benefits to the very real ways these systems can encourage overtrust. They talk through how “hands-off” can become “mind-off,” why supervising automation is harder than it sounds, and where responsibility really lies when things go wrong.  Other topics: 🔹 The big U.S. city we DON’T want to live in 🔹 The Apple TV show Shrinking & the collateral damage of fatal crashes 🔹 We then open up the mailbag to answer some listener questions Subscribe for biweekly conversations about all things transportation.

    Episode 19: Pedestrian Deaths are Finally Dropping? + Johnny Transportation Comes to Town

    Pedestrian Deaths – David & Wes dig into a surprising shift in pedestrian safety and ask a harder question: are streets actually getting safer, or are we just seeing a temporary drop in risk? After years of rising fatalities, recent numbers suggest a modest improvement, but the pattern is anything but consistent. They explore whether this reflects real progress from design changes and enforcement, shifting travel behavior, or simply volatility in a system that still produces predictable danger. It’s a conversation about what it would actually look like if we knew how to make streets safer, and why the data do not quite tell that story yet.

    Episode 18: The Upside of High Gas Prices + 190 MPH down Pennsylvania Avenue

    Gas Prices – David & Wes dig into the upside of high gas prices and why the story is more nuanced than it often seems. While rising costs at the pump can create real challenges, they also explore how higher prices can make other modes more attractive, reinforce location efficiency, and shift how people think about transportation more broadly. It’s a conversation about how gas prices shape behavior, influence our transportation system, and what gets lost when we only talk about them as a political problem.

    Rural AVs – David & Wes take a deep dive into the future of rural transportation and why mobility challenges outside our cities deserve far more attention.
