I used to be able to take BART to work. Half hour each way. But it was also a half hour walk each way on both sides. So total commute was 3 hours.
So there is a good reason why there is a push to force cities to allow multifamily developments within quarter to half a mile of mass transit. Personally I don't think this can be mitigated on the city level. Especially in a fractured metro like the Bay Area. You have six counties, three major cities and two dozen small cities and towns.
