I've noticed interesting trends in the Bay Area. Up until about three weeks ago, traffic during rush hour was lighter than pre-pandemic. But about three weeks ago, traffic in the south bay (specifically 280N from 85 to 101) has returned to pre-pandemic levels.
However, just last week I drove home from SF to Cupertino at 5pm and did it in 54 minutes (which is basically $min_time). Pre-pandemic that drive would have been 90+ minutes.
