Lane-Split Logic

Traffic congestion is choking modern cities-burning fuel, polluting the air, and stealing hours from our lives. Yet one proven, low-cost solution remains underused and misunderstood: allowing motorcycles and scooters to move efficiently through traffic via lane-splitting and filtering. Lane-Split Logic delivers a fact-first, global examination of how these practices, when done within clear rules, can dramatically improve traffic flow, cut emissions, and make streets safer for everyone. Drawing on peer-reviewed research, official crash data, roadside emissions studies, and real-world policy examples from California to Manila, Taiwan to Paris, this book dismantles myths and replaces them with hard evidence. From the physics of traffic flow to the human factors of mirror checks and predictable behavior, Lane-Split Logic shows why narrow-footprint vehicles are a vital part of sustainable urban mobility. It's not just about motorcycles-it's about reclaiming road space, reducing environmental harm, and building a culture of predictability where every road user knows what to expect. Whether you're a policymaker, transport planner, safety advocate, or simply a driver tired of being stuck in gridlock, this book will change how you think about the future of our roads.
