from a fair bit of the LA area, you can do burbank/long beach to oakland/san jose/sfo (though fog delays are common to sfo) and access a fair bit of the bay area in ~3 hours of commute time each way. not ideal, but once a week would be tolerable for many folks. i’ve done that day trip a number of times (though not weekly), and have known folks who did that (or the reverse) on a weekly basis.
