Tailgating won’t get you through that intersection any faster

You’ve stopped barely a hair’s breadth away from the car in front of you at a traffic light, hoping to get through quickly when the light changes. But you won’t. Instead, a new study suggests you’ll take just as long as an auto stopped up to two car lengths behind the lead driver. To find out whether tailgating pays off, researchers lined up 10 sedans at a traffic intersection on a test road, such that they stood different distances apart each time. A drone hovering above the intersection recorded the cars moving as the light turned green.
