Episode 25: How Stressful Is Your Bike Ride? + Bike Lane Camera Enforcement
Bike Stress - David & Wes talk about bike route stress and a major blind spot in the existing Level of Traffic Stress method: intersections. The current approach does a good job rating street segments, but it largely ignores exactly where a route can become far more stressful in real life. David & Wes discuss a new survey designed to help fix that gap by bringing intersections into the mix, and why better bike safety analysis depends on measuring the full route, not just the links be…
Episode 24: Crash Data Blind Spots + Who Gets to Use Public Roads?
Crash Data Blind Spots - David & Wes dig into crash data and why Americans may know less about road deaths than we think. Everyone says they want data-driven safety policy, but the data we rely on often miss major categories of harm, including crashes on private property, parking lots, driveways, and behind gates. They talk through what gets counted, what gets left out, and why police-collected crash data can turn a partial record into something that looks more complete than it really is…
Episode 23: World Cup Transportation Culture Shock + Safety Rituals That Stop Making Sense
The World Cup - David & Wes mark the start of the World Cup by talking about the transportation culture shock many international visitors may experience in the United States. From stadium access to transit service to the everyday assumptions baked into how we move people around big events, they discuss why hosting a global event can expose the gaps in our transportation system. It’s a conversation about what happens when the world arrives expecting world-class mobility and instead encoun…
Episode 22: The Gas Tax Holiday Trap + How Singapore & Fargo Price Transportation
Gas Tax Holiday - David & Wes take on gas tax holidays and why cutting a few cents from the price of gas is usually better politics than transportation policy. The federal gas tax has been stuck at 18.4 cents per gallon since 1993, and suspending it would barely make a dent in a fill-up while weakening a transportation funding system that is already running on fumes. They talk through who actually benefits, whether the savings ever reach drivers, and why a real price-stabilization policy…
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 d…
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, wh…
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.

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 …
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 …
