While it's theoretically possible to block roads to prevent the movement of vehicles, doing so on a large scale presents significant logistical challenges that could weaken an authoritative regime. Roadblocks require personnel, materials, and continuous maintenance to remain effective. Every blocked road would require surveillance and manpower to enforce the restrictions, diverting resources from other operations. Moreover, road networks are often intricate and expansive, providing multiple alternative routes that would also need to be blocked and guarded. The sustained effort required would strain any regime's resources, making it a less viable long-term strategy for maintaining control. Additionally, while blocking foot traffic might be "harder," it's crucial to recognize that pedestrian movement has its limitations in speed, distance, and the carrying capacity for supplies. The argument for the "difficulty" in blocking foot traffic seems to overlook these inherent limitations, which can be just as easily exploited to contain and control a population. For instance, restricted zones, barricades, or even curfews could be implemented in walkable areas to deter foot movement. And unlike vehicles, individuals on foot are far more susceptible to environmental factors like weather, further limiting their effectiveness in a scenario requiring rapid mobilization. Contrary to the notion that cars are easily contained, their speed and range offer a unique form of decentralized power. The very act of needing to block roads to contain vehicular movement is a testament to the car's potency as a tool for mobilization and resistance. Therefore, while no method of transportation is completely impervious to control, the ability to move freely in one's own vehicle still offers a degree of autonomy and flexibility that can be crucial in challenging situations.
