Final answer:
Traffic backlogs caused by gawking are a major cause of traffic congestion in busy urban areas during rush hour. They disrupt the flow of traffic and result in long delays, frustration, and increased air pollution and fuel consumption.
Step-by-step explanation:
The correct answer is option Traffic congestion. Traffic backlogs caused by gawking are a major cause of traffic congestion. This is commonly observed in busy urban areas during rush hour, when drivers slow down or stop to look at accidents or other distractions on the road.
Gawking causes a ripple effect, as one driver slowing down or stopping can disrupt the flow of traffic behind them, leading to a chain reaction of congestion. This can result in long delays, frustration, and increased air pollution and fuel consumption.
For example, in cities like Washington, D.C. and Los Angeles, traffic congestion is a significant problem due to factors such as heavy traffic, long commutes, and sprawl. Similarly, in India's urban centers, traffic congestion is a daily reality with slow speeds and idling vehicles contributing to increased pollution and carbon footprint.
