Road rage has many harmful manifestations: the most rampant of which is tailgating.

It turns out, people who drive sports cars tailgate twice as much, on average, as people who drive family cars, like minivans. A recent study, published by smartmotorist.com, suggests that drivers of specific types of vehicles are more prone to tailgating than others.

Tailgating is one of the most infuriating things fellow drivers can do to you out on the road. When the speedy culprits tailgate, though, they’re also putting themselves at immense risk. They’re significantly decreasing their chances of coming to a safe stop -- cutting their stopping distance -- if the drivers in front of them come to a sudden stop.

One important thing to note about tailgating, and something many drivers don’t realize, is that stopping distance is different for different sized cars. The stopping distance for a heavy-duty truck is much longer than it is for, say, a Mini Cooper. It actually takes a truck twice the distance to stop than it does a regular passenger vehicle. All passenger vehicle drivers should make sure to keep a safe three-second stopping distance.

The study conducted by smartmotorist.com gets even dicier, though, when it breaks down tailgating statistics by gender.
