The potential benefits of self driving vehicles include

• A. Improved traffic flow
• B. Increased fuel consumption
• C. Higher accident rates
• D. Reduced road maintenance costs

Answer: (A)

Self-driving vehicles improve traffic flow by coordinating speeds and spacing, often through vehicle-to-vehicle communication and advanced cruise control. This reduces stop-and-go driving, smooths merges, and allows more vehicles to move efficiently, which lowers congestion and travel times. The benefit is most direct: steady, predictable traffic increases road capacity and reduces wasted time. Increased fuel consumption isn’t aligned with how autonomous systems optimize acceleration and routing; higher accident rates would contradict the safety advantages; while road maintenance costs might change in the long term, they’re not the primary, consistent benefit described by these systems. So the best-fit benefit is improved traffic flow.
