I wonder how a route suggesting app, that accounts for traffic, avoids the El Farol Bar (lets call it EFB) problem. EFB essentially is people in the town of El Farol want to have a good time, and they the option of staying at home or going to the one bar the town has. If a lot of them end up at the bar, people would have had a better time staying at home. And if a lot of them stay at home, the bars are not crowded and they&#x27;d have had a better time in the bar.<p>The catch is no one knows in advance who is going to go the bar. It can be shown that no pure strategy can work for EFB.
