Final answer:
True, rubbernecking, unnecessary lane changes and tailgating are significant contributors to traffic congestion as they disrupt the movement of vehicles and increase the risk of accidents.
Step-by-step explanation:
Rubbernecking, unnecessary lane changes in attention, and tailgating are indeed some of the main factors that contribute to creating chronic traffic congestion. these behaviors can lead to reduced road capacity, erratic traffic flow, and increased risk of accidents, which in turn cause slowdowns and backups. Rubbernecking, or slowing down to look at accidents or distractions, can cause a ripple effect slowing down traffic behind the rubbernecker. Similarly, excessive lane changes can disrupt the flow of traffic, prompting other drivers to adjust their speed or change lanes as well, leading to traffic jams.
Tailgating increases the risk of rear-end collisions, which can also result in traffic congestion due to lane closures or slowed traffic passing the accident scene.
