Micromobility is often discussed in the context of minimizing traffic congestion and transportation pollution by encouraging people to travel shorter (i.e., typically urban) distances using bicycle or scooters instead of single-occupancy vehicles. It is also frequently championed as a solution to the “first-mile/last-mile” problem. If the demographics and intended users of micromobility vary largely by community, surely that means we must identify different reasons for using micromobility. Micromobility, User Input, and Standardization considers potential options for standardization in engineering and public policy, how real people are using micromobility, and the relevant barriers that come with that usage. It examines the history of existing technologies, compares various traffic laws, and highlights barriers to micromobility standardization—particularly in low-income communities of color.

Modern in-vehicle experiences are brimming with functionalities and convenience driven by automation, digitalization, and electrification. While automotive manufacturers are competing to provide the best systems to their customers, there is no common ground to evaluate these in-vehicle experiences as they become increasingly complex. Existing automotive guidelines do not offer thresholds for cognitive distraction, or—more appropriately—“disengagement.” What can researchers can do to change this? Evaluation of the In-vehicle Experience discusses acceptable levels of disengagement by evaluating the driving context and exploring how system reliability can translate to distraction and frustration. It also covers the need to test systems for their complexity and ease of use, and to prevent users from resorting to alternative systems while driving (e.g., smartphones).
