Look Both Ways with David & Wes

Culture Wars - David & Wes ask how transportation became another front in the culture wars. From transit funding & electric vehicles to DEI bike lanes & rainbow crosswalks, they explore why all this has become a test of political identity. But this is about more than words. What happens when safety improvements become political targets, and all of the sudden, solid evidence that a project works isn’t enough to save it? They look at how we got here, why these fights extend beyond the U.S., and what it would take to put people’s transportation needs ahead of blue/red loyalty. Topics include: 🔹 Examples of America's growing partisanship in transportation 🔹 Its impact on road safety & our streets 🔹 A look at some related international issues Also, please come vote on which stickers we should make! www.lookbothwayspodcast.com Subscribe for biweekly conversations about all things transportation.

Gas Prices - David & Wes talk about high gas prices and whether the changes they prompt will stick. Some people try transit or bicycling. Others start shopping for an EV or a hybrid. But what happens when gas gets cheaper again? The conversation then turns to the shrinking value of fuel taxes as well as a question that many people think they already know the answer to: who pays for our roads? Sure drivers contribute through gas taxes, tolls, and fees, but that doesn't come close to covering the bill... Topics include: 🔹 David's trip to London 🔹 Gas tax holidays & if they help the cause 🔹 Oregon’s pay-per-mile program & whether road usage charges are a better way forward 🔹 The future of the federal gas tax 🔹 The myth that drivers pay for roads Subscribe for biweekly conversations about all things transportation.

Climate + Transportation - David & Wes kick things off with a good conversation about the irony of Waymo sponsoring Climate Week events. Electric robotaxis may be cleaner than gas-powered car trips, but that does not mean they help the bigger cause. The harder questions are about what kinds of trips they replace, whether they create new vehicle miles, and whether AVs reduce driving or simply make car travel easier to justify. From there, the discussion turns to regional rail and the role it could play. Topics include: 🔹 Our most miserable travel experiences 🔹 Waymo, Climate Week, & the greenwashing question 🔹 Electric AVs & the problem of more vehicle miles 🔹 Colorado’s growing interest in regional transit & passenger rail 🔹 And send your Look Both Ways sticker ideas to [email protected] Subscribe for biweekly conversations about all things transportation.

Speed Limits - David & Wes talk about speed limits: what they can do, what they can’t do, and the surprisingly complicated question of how robotaxis should handle them. Japan is moving toward lower speed limits on a large share of its roads, shifting many streets from 60 km/h to 30 km/h. That sounds simple enough, but speed is never just the number on the sign. It looks different from behind the windshield, in the crosswalk, inside a traffic study, or at the moment of impact. From there, David & Wes get into the 85th percentile, why traffic engineering has often treated driver comfort as data, and whether AVs should strictly follow the law, move with traffic, or behave the way human drivers actually do. Topics include: 🔹 Car commercials that made us mad (or happy) 🔹 Why speed feels different from inside and outside the car 🔹 The 85th percentile trap 🔹 Robotaxis, speed limits, and the weirdness of legal compliance 🔹 And send us your Look Both Ways sticker ideas!

Senior Mobility - David & Wes talk about older drivers, road safety, and the uneasy idea of “driving forever.” Wes starts with a paper he co-authored about how people think about driving, aging, and the possibility that they may someday need to give up the keys. But the point is not just what happens when someone can no longer drive; it is what happens before that. David then talks about visiting his parents’ retirement community, where slow streets, golf carts, and walkable destinations offer one version of what can come after driving becomes less central. But even there, the tradeoffs are real (and one neighbor bought a Tesla hoping Full Self-Driving might help him keep going). That opens up a bigger conversation about safety, independence, loneliness, family, and what life after driving can actually look like.

Global Road Safety - David & Wes take a global view of road safety and ask why the United States keeps falling behind. They start with the U.S. being the only country to vote against a United Nations road safety declaration, then turn to a more uncomfortable comparison: the U.S. now appears to have a worse per-capita road fatality rate than Russia. From there, they look at the widening global road safety gap, including countries that once had worse safety records than the U.S. but have since lapped us. They also talk about Pontevedra, Spain, a city that dramatically reduced car dominance and has not had a road fatality since 2011.  Today's topics: 🔹 Why the U.S. voted against a global road safety declaration 🔹 How Russia’s road safety record compares to the U.S. over time & countries that used to be more dangerous than the U.S. but are now far safer 🔹 Why “car-free” cities like Pontevedra still have cars 🔹 Monster truck rallies, obviously Subscribe for biweekly conversations about all things transportation!

Transit Funding Freeze - David & Wes dig into our frozen federal transit funding situation and what happens when major transit projects are not officially killed, but also are not allowed to move forward. After new reporting on the Trump administration’s apparent halt in final agreements for Capital Investment Grants, they talk about what these delays mean, why stalled transit funding makes projects more expensive, and the hard reality that cities can no longer assume the federal government will be a reliable partner.  Other topics: 🔹 Lebron’s new commute 🔹 FHWA’s Proven Safety Countermeasures website & the disappearance of road diets and speed safety cameras 🔹 Bicycling disappearing from FHWA’s proven safety countermeasures, along with the infrastructure that helps make biking safer 🔹 Why Waymos are still blocking bike lanes (and what to do about it) 🔹 We also answer a couple mailbag questions and, for some reason, talk more about Fabio Subscribe for biweekly conversations about all things transportation!

Tire Pollution - David & Wes look at tire pollution and why the harms may be broader than most people realize. What started as a story about 6PPD-Q washing into streams and devastating coho salmon is now raising new questions about human health, including a recent study linking tire-related pollution to Alzheimer’s-related pathways. They talk through what we know, what we still do not know, and why tire wear should be part of the transportation pollution conversation, even in a world with more electric or autonomous vehicles.

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 between intersections. Other topics: 🔹 The bike tours we wish we could take (or not) 🔹 Bike lane cameras & whether automated enforcement could/should keep bike lanes clear 🔹 Some fun mailbag questions from listeners Subscribe for biweekly conversations about all things transportation!

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. It’s a conversation about why better road safety depends not just on having data, but on understanding where that data comes from, who collects it, and what it fails to see.
