Here's a fun riddle for your Wednesday commute — assuming you're not still stuck on the 101. Silicon Valley's population dipped during the pandemic. People left. Remote work boomed. The great exodus was real. So why does it feel like traffic has somehow gotten worse?

The answer, like most things in the Bay Area, is more complicated than any one headline suggests — and it has a lot to do with how we collectively decided to respond to the post-pandemic world.

First, the population narrative is more nuanced than "everyone left." The pandemic drop-off has largely reversed. People came back — or new people filled the gaps. But more importantly, the people who did leave often didn't leave the Bay Area entirely. They just moved further out. Cheaper rent in Tracy, a bigger house in Stockton, a yard in Sacramento. The jobs stayed in San Jose and Mountain View. The commutes got longer.

As one Bay Area commuter put it plainly: "People live further away from their work and more people go to work than before."

Then there's the hybrid work factor. Nearly every major tech company now mandates roughly three days in the office. And here's the behavioral quirk nobody in city planning accounted for: people who only commute three days a week are far more willing to drive those three days instead of investing in transit passes or building routines around Caltrain. As one local noted, "People are willing to sit in traffic when it's only 3 days of commuting."

So we ended up with the worst of both worlds — fewer consistent transit riders gutting public transportation revenue, and more cars flooding the highways on the same peak days. Tuesday through Thursday on 280 is now a special kind of hell.

This is what happens when you spend decades underinvesting in transit infrastructure and then act surprised when people default to their cars. BART and Caltrain needed riders to survive. Hybrid work scattered those riders. And instead of adapting with flexible pricing or better service, our transit agencies are mostly just asking for more taxpayer bailouts.

The population didn't really shrink. It just rearranged — and our infrastructure, as usual, wasn't built to handle the change.
