    No s&^t. Just drive on an interstate to see this.

    So what you’re saying is, the solution is to always carry around a rocket-propelled-grenade and to immediately blow up any vehicle traveling slower than you wish to travel.

    …or am I missing something?

    I would like to see this experiment tried with automated vehicles. Could traffic jams be prevented if you take the human being out of the equation?

    We call it here the caterpillar effect. It is quite common here in Portugal, because we drive glued to the rear end of the next car. (Being a Latin Southern Europe country with an individualistic, opportunistic culture, if you pace your driving and keep some distance from the car in front of you, there’s always some “schmuk” that wedges in. Always.)

    #3 Absolutely.

    This is easily explained: It’s faster to brake than to regain speed. So when there’s variations in speed and cars clump together, the tendency is to stop. That produces a Jam that grows as there is similar density traffic behind.

    This study did not mention if all the vehicles had the speedometers calibrated. They also didn’t say how many drivers were on their cell phones.

    Then people wonder WHY I like speeders…
    they GET to the inside and get OUT OF THE WAY.
    Even if 10% got OUT of the way, it would lessen the impact.
    It should be, SLOW lane, FASTER lane, REAL fast lane..
    But they DONT DO THAT. Some ODDBALL gets int he FAST lane, because he dont like sitting BEHIND other drivers, and he is only DOING the speed limit.

    And what? Do they have a solution?

    Explains a lot.

    Doesn’t make my morning commute any better though!

    I wonder how increasing the speed limit, and/or setting a minimum speed would change the equation.

    Are there traffic jams on the Autobahn’s of Germany?
