The consumption of **alcohol** while driving is extremely dangerous because it negatively affects the driver in several aspects:

- **Behavior:** Alcohol generates a **false sense of security**, leading to **overestimating one's abilities** and **disregarding danger**. This can cause the driver to take more risks and make more mistakes that can lead to accidents.

- **Perception of the environment:** Under the effects of alcohol, there is poorer vision of traffic signs and traffic lights, and misjudgment of the distance to other vehicles. Additionally, there is a higher probability of experiencing distractions and glare.

- **Movements and decisions:** Alcohol impairs the coordination of movements and increases the time needed to react. It also raises the likelihood of making poor decisions or not knowing how to execute them correctly.

In summary, alcohol affects the brain and vision, leading to a misperception of one's abilities and an underestimation of dangers while driving. Therefore, the statement that the driver overestimates their abilities and disregards danger is correct.
