Does alcohol induce excessive self-confidence in a moped driver, which leads to bravado on the road as well as impairs distance assessment and increases reaction time?

Alcohol, by acting on the central nervous system, significantly impairs the psychomotor skills necessary for driving a vehicle. It increases reaction time and impairs the proper judgement of distance, while at the same time reducing the capacity for critical thinking, which creates a false sense of confidence and a tendency towards recklessness. All of the factors mentioned in the question are typical and very dangerous consequences of a driver consuming alcohol.
