What substantial factor related to novice driver crash incidents is an overestimation of ones own driving?

An overestimation of one's own driving abilities is a substantial factor contributing to novice driver crash incidents. Many inexperienced drivers believe they are more skilled than they actually are, leading to risky behaviors such as speeding or underestimating the importance of following traffic rules. This overconfidence can result in poor decision-making and an inability to accurately assess dangerous situations, significantly increasing the likelihood of crashes.
