The authors assumed that every car has the same effect on the travel time of other cars. This assumption is evident in their analysis of the impact of car volume on traffic congestion. It is known that different cars have different capacities to cause traffic jams, such as larger commercial vehicles versus smaller passenger cars. Therefore, assuming that every car has the same effect on traffic is unrealistic.
