While the mandate is convincing that the writing on the wall for gas-powered vehicles is imminent, it is too early to at least make it a mandatory mandate for a state. The market and demand for electric vehicles are not yet high enough to consider a necessary mandate. Rather than implementing this, the state should promote the benefits of electric vehicles and allow tax incentives for citizens who own electric vehicles to slowly build up a sizeable population of electric vehicle owners. That way when a good sizeable amount of owners is enough for a state like California, then the mandate can go through.
