No, tailgating doesn’t get you where you need to go faster

A study published on Thursday (Dec. 14) in the journal IEEE Transactions on Intelligent Transportation Systems uses mathematical simulations to show that tightly following a car in front of you will only worsen traffic jams. Instead it proposes that drivers adjust their position based on both the car in front and behind to keep traffic flow smooth. This small behavioral tweak could as much as halve commute time on certain roads.
