In the past I feel like people drove down the main streets but now, when the main street fills, Google Maps, and probably Apple Maps and the rest, redirect cars to streets with less traffic. Those streets then end up pouring cars into the the main streets further down, jamming up the entire system.

I have no data, it's just a thought as I see the grid lock and every small side street full of cars. I see the main streets going super slow as people from the packed side streets push back into the main streets they avoided earlier. That means the main street itself is running 10x slower than it would otherwise, at least toward the start, as each car that enters at the start has to wait for the hundreds of cars merging in from side streets in front of it. Cars that were not doing that from side streets 20 years ago because their GPS maps were not directing them to
