A man in his 40s driving a Maserati under the influence of alcohol caused an accident in Gangnam, Seoul, colliding with a motorcycle, bus, and taxi in succession. The motorcycle rider died as a result of the accident, and three others, including a bus passenger, taxi driver, and pedestrian, were injured. The drunk driver's blood alcohol concentration was measured at a level that would result in license revocation, and police are currently investigating whether he was also driving under the influence of drugs.
