i didnt have to read the link to know what it said. ask jinx. i've been commenting on this effect for years. one asshole can spill his coffee, and there will be waves for hours. i try to keep a steady speed to "erase" the waves when i can. i love the gif on the top of the page, it looks just like i imagined it in my little pea sized mind.

it's about cumulative reaction time lag. i try to look at the car in front of the one i'm following for my cues. keeping a peripheral focus on the one right in front for any unexpected idiocy, of course ( is that an oxymoron when the topic is traffic?...."unexpected idiocy", that is)
