Berkeley to Moffett?
Gee, when we got married my wife commuted from Walnut Creek to Los Altos. Sometimes I'd drive with her at 6 and then Caltrain up to SF, then take bus to market street.
I'm not too sympathetic, my friend.
CT Jr tells me that cal students get free Public Transportation of some sort. She barts to SF.
Thus, you can tell SCT Jr to bart to the intermodal station near SFO (Milbrae?) and then Cal Train south, and then ride his electric bike to Moffett.
He will be able to sleep and do all his work on the trains.
Beats the soul-crushing traffic. But being a Bay Area guy, it is what it is. Commute in off hours if you opt the car option. It's doable. He's young, these are the things he needs to overcome.
If the opportunity is temporary and a good career move, this is nothing. Buckle up.
