The science is settled:
Deep in your heart you know it: there are like two drivers out there on the road that are causing all the traffic jams and one of those assholes is the guy right in front of you. Well, new information collected from hundreds and hundreds of drivers’ cellphones actually backs that up. Sort of. It turns out that it takes very few jackasses to screw things up for everyone.
In a study conducted by MIT and Berkeley, 680,000 Boston commuters were tracked along their commutes—anonymously—as their cellphones jumped from tower to tower. The resulting data gave a better picture of commuter habits than any old-fashioned survey had in the past. During rush hour, a massive 98 percent of roads were below peak capacity. But the two percent that were over capacity were enough to cause traffic jams that spiraled out into the less crowded roads. Granted, not all cities are the same, but it goes to show the potential power of just a few crowded streets.
And a few jerks behind the wheel.
