I would make single car trains that are built by tesla and go exactly where you need. Need to go directly to Fremont? Get on a train that is routed directly to your destination with other patrons from Embarcadero to Fremont. No unnecessary stops. This would require infrastructure for stations to include "offramps", but with a modular bus system (think uber), your ride would be available at the Fremont station waiting to take you the last few miles.
