I am glad there is finally a website dedicated to this issue, although I'm afraid that most of the people who cause traffic problems like this won't read that site. I like this, in reference to the animated image you see there: "Remember that milliseconds can add up to gridlock."
Do you know what I see a lot of around here? People driving very slowly, five or ten or fifteen miles per hour under the speed limit, running red lights. Not only do they drive slowly and make everyone else wait, but they then break the law to avoid the consequences (i.e. the delay) of their inability to drive like a normal person.
