In this episode of Look Both Ways, David & Wes explain why an online kerfuffle about autonomous vehicle safety unexpectedly put David himself in the spotlight. They unpack why autonomous vehicle debates so often generate more noise than insight, how narratives take on a life of their own, and what cities should be paying attention to right now. Listeners will come away with a clear sense of where autonomous vehicles truly stand and why context, logic, and governance matter more than bold promises.
