> Some places live traffic information gives you a choice between a 10 minute way and 40 minute way though

I lived in one of those alleged places (Chicago) and didn't observe this in practice. When Google sees that 10-minute route, it quickly starts routing drivers that way, and eventually both routes equalize around, say, 30 minutes. When two routes are that disparate, by the time you actually get midway through the faster one, it's just as congested as the slower route.

I think there's a weird psychology to these apps. When Google gives you a wack route through a residential area, it feels like you're getting an advantage. It feels like you're beating traffic. But you never beat traffic in a car, because you are traffic. And Google never sends only one car on a faster detour. It was always half a dozen of them or more. I saw this a million times in Chicago.

Getting pretty local here, but I remember one of Google's favorite alternate routes vividly. Instead of taking the Edens south into the Kennedy junction, it would have you exit onto Foster and then take some rando residential street south to Montrose or Irving Park. Every single time it did this, I'd see a parade of cars in front of me and behind me. The white glow of GMaps on a new car's infotainment screen is unmistakable. I could see what was going on, all of us could see what was going on. Meanwhile, you're driving past a bunch of kids waiting for their bus, or a ride home from school, and those are all delayed because me and a hundred others are using a side street as a commuter artery. This saved, on a good day, five minutes on a 35 minute commute. It was more antisocial than it was efficient.
