They also need to get the roads, busses and ferries on board with this plan.
The goal (by law) should be twofold:
1) increase the number of people with a 90th percentile commute under 15, 30 and 60 minutes. (i.e., improve quality of life and encourage economic growth)
2) sharply reduce the average CO2-equivalent emissions of each commuter.
The current statewide policy (by law) is to reduce commute miles.
In practice, this means intentionally sabotaging commute corridors, which slows economic growth (fewer available workers and fewer reachable jobs) reduces quality of life and increases CO2 emissions (due to repeated idling and hard acceleration).
