I'm not sure I completely agree with Hugo, but his inputs are worth considering.
I live NE of Sacramento, exactly 125 miles from the SFO employee lot.
Especially since Covid, things have not been too bad. Last Friday, I crossed the Bay Bridge at 0710 (without extra pax, so no HOV) and only waited about 10-15 min at the toll booths. That was the only traffic I hit.
I leave home ~4 hours to show and it's comfortable. That includes the 25 minutes to leisurely find a good parking spot, change into my shirt, and walk to Ops.
I don't recall having any flow delays going into SFO over the past 6 years that affected my return.
Driving from SFO up I-80 to greater Sac can be longer if you are leaving SFO after around 1530 on a weekday.
And for heaven's sake, don't try to drive to Oakland or SFO on a Sunday afternoon most of the year. Everyone is coming down the mountain and I-80 is a mess.
