I’m never really sure how Google knows what is going on. I mean, they could have a lot of really smart people that research issues and make predictions. They could collect a lot of data and then use it to predict trends. That was the conclusion of classical mechanics as I understand them: If you knew the location and velocity of every particle, you could predict everything that was to come. Further research has shown that you can’t know both pieces of information, but still Google is able to predict, almost to the minute, how long it will take me to drive up to Sacramento to hang out with my friend Dan and cover the SAWS Challenge, a 5 round Warhammer Fantasy Grand Tournament. Google Maps put the drive at 2 hours, 10 minutes. I would be leaving San Francisco on a Friday evening, so traffic would be rough. Maybe the estimate went up. I ride a motorcycle and can cut through most of it, so maybe the estimate went down. I would be taking 80, and there was road construction, so the estimate goes up. It’s 80, so people are going like 75 mph, so the estimate goes down. I got lost and had to stop and look at a map, estimate goes up. Still, 2 hours and 10 minutes later, there I was, at the hotel, right at the time Google had told me I would be there. Can they manipulate traffic signals to control this flow of cars? Did they turn off the lights of the signs that would have guided me? All good questions for another time.
