Final answer:
The term is road rage, which is a form of hostile aggression manifested in aggressive driving behaviors, including carrying a weapon and deliberately targeting other vehicles on the road.
Step-by-step explanation:
The term for a degree of aggressive driving where the driver carries a weapon, deliberately bumps or rams another vehicle, tries to run a car off the road, or uses a weapon is road rage. This kind of behavior is an extreme form of aggression, indicating hostility and the intent to cause harm or pain to others. Road rage, unlike reckless or distracted driving, is motivated by anger and involves direct, sometimes violent, actions against other drivers. Hostile aggression is a form of aggression motivated by feelings of anger with the intent to cause pain, while instrumental aggression involves behavior intended to achieve a goal and may or may not involve the intent to cause pain.
