As he said it, the twenty-six lanes of the Katy Freeway suddenly filled up with cars and trucks, countless thousands of them, moving along at moderate speed—not quite a traffic jam, but still with enough brake lights igniting here and there to temper the flow. A motorcycle weaved through, going twice as fast as everyone else, using the bigger vehicles as pylons. The illusion was powerful even though the rendering had been simplified—every semi was a clone of a simple featureless semi model, and the same was true of cars, vans, pickups, and so on. But if anything that simplification made it easier to "read" the data. T.R. was showing them, in a way that was easy to grasp, exactly how much traffic had passed down this freeway at this time of day on this day of the year in 2019.
