I recently had to drive to the Philadelphia Airport to drop off/pick up some folks. Here in the Lehigh Valley I’m roughly an hour north of the city of brotherly love. Like most sentient drivers, I’ve come to rely on GPS navigation. Dropping off my parties turned into a nightmare of congestion. The GPS solidly insisted that the turnpike, 476, was the “fastest” way. One thing AI doesn’t understand is how people behave. The flight required dropping off a couple hours before that known as “rush.” 476, once yet get near Philly has several pain points where traffic merges on from several ramps onto an already crawling stream of traffic. That’s human behavior—never considering that the “longer time” route might actually be quicker. Or at least a touch easier on the blood pressure. Of these thousands and thousands of people, relatively few were going to the airport. Once I got home from a journey that Al told me would be two-and-a-half hours, round trip (which was actually three-and-a-half), I began looking for alternate routes for pick up.
Pulling up the usual map app on my laptop, the only route shown was the turnpike, clearly not designed for this volume of traffic. Not being native to Philadelphia, I don’t know my way around very well. Then I began to lose trust in Al. Interstate 95 also goes right by the airport. I force-dragged the route over that way. The estimate? Maybe fifteen minutes longer than the turnpike. AI doesn’t understand that people who know the turnpike is a bad idea at this time of day will take it anyway. It is the “fastest” way to where you’re going. And who wants to waste time?
Me, I’d rather not shave off so many years of my life. I’m not so foolish as to suppose I-95 would be much better, but with the “real-time” facts added in, it might very well save some time, and gray hairs, to go the somewhat longer, slower route. Al didn’t even want to tell me that was an option. Who could possibly want to go on at a slower pace, for mental health reasons? Even en route it will try to reroute you back onto “the fastest” way that it clearly misunderstands. I remember driving in Newark, Seattle, Boston, Chicago, Milwaukee, Pittsburgh, and, briefly, New York City. Those who write algorithms are missing something basic. Human psychology plays into this in a major way. Al is not human nor does it “think.” It calculates. As for me, I calculate that the slower way may just be what the doctor ordered.
