In order to solve the problem of urban traffic congestion, the government in some places has continuously widened and built new highways, but these newly built roads were quickly flooded with traffic, and the traffic congestion situation has not only eased, but has become increasingly serious. Which of the following, if true, is the least helpful in explaining this phenomenon? ['The minimum speed limit of newly built highways is higher than other highways.', 'The new extension of roads will induce people to buy and use more cars.', 'New extension of highways will lead to an increase in residential and commercial areas along the route.', 'People tend to drive on newly built highways.']
