Your daily commute traffic differential

That was my second guess. First was Bay Bridge. Yours is truly a nasty commute.

I leave for work around 6:25AM – it takes 20 minutes, depending on the lights.

At 5AM I could make it in 15 minutes.

I work 9-5. Week days about 20 to 25 Minutes depending on lights and traffic.
Nights or week ends 10 to 20 depending on lights

-5 to -10 minutes. I commute by train. During business hours, I don’t even look at the train schedule, they run every couple minutes. From home to work or work to home, it is abut 45 minutes from door to door, including the walks to and from the train stations.

On weekends, the train runs frequently, but more like on an every 8-10 minutes schedule. Overnight, I think it’s every 20-30 minutes.
