I've got a friend in the Roseville area. While on probation, he would go sit short call in Vacaville or Travis AFB, since he did not want to push things.
With no traffic, you can get from the intersection of I-80 and Hwy 65 to the SFO employee lot (118 miles) in about 1+50. Right now (at 1425 on Memorial Day), it would be 2+40. Sunday afternoon is the worst time to drive to the city. And it once took me 1+25 to get from the Bay Bridge toll booths to the employee lot... 20 miles.
After a red-eye, driving back home means no traffic at 0600, and once again, you can get to the 80/65 interchange in a touch under two hours.
As Capt Fitz says, factor in 20-25 minutes from the time you enter the parking lot until you're standing in SFO Ops.
I personally think sitting short-call reserve in Roseville or further is pushing it... but I know pilots that do it.
