Is it a fact or fiction that "my vehicle can stop just as fast as the one I'm following"?

The statement "my vehicle can stop just as fast as the one I'm following" is considered fiction because it oversimplifies the complexities of vehicle dynamics and braking systems. Different vehicles have varying stopping distances due to numerous factors, including their weight, braking systems, tire condition, and road conditions. For instance, heavier vehicles typically require more distance to stop compared to lighter ones, and the effectiveness of brakes can vary widely across different makes and models. Additionally, environmental factors like wet or icy roads can further influence stopping ability, regardless of the capabilities of the vehicles involved. Understanding this concept is essential for defensive driving, as it emphasizes the importance of maintaining a safe following distance to account for potential differences in stopping capabilities among vehicles on the road.
