What mobility-related issue has caused concern among urban planners regarding the automobile-centric model?

The automobile-centric model has raised significant concerns among urban planners primarily due to urban congestion and pollution. As cities have developed around automobile use, the heavy reliance on cars has led to increased traffic congestion as roadways become overcrowded with vehicles. This congestion not only causes delays but also contributes to higher levels of air pollution, which negatively affects public health and the environment.

Moreover, the prioritization of automobiles often limits the development of pedestrian-friendly spaces and reduces the quality of life for residents. Urban planners advocate for more sustainable mobility solutions that can minimize congestion and mitigate pollution, such as public transportation, biking infrastructure, and walkable city designs. This shift aims to create a more balanced transportation system that addresses the adverse consequences associated with an automobile-dominating approach.
