Without BART, will you still go to work?

Nope. I telecommute a couple days per week already, but when I go in I take BART or AC Transit Transbay buses. The bridge is going to suck. I'll WFH until they figure it out.

I'm going to be WFH since I need to go from Berkeley -> San Mateo and the drive will be heinous with all the additional cars.

I'll still go, but only because I work in San Mateo and live in SF. Caltrain will be my friend.
