The appears to be another goal that can’t be achieved. CARB (California Air Resource Board) put out a report last year that said that “zero-emission vehicles (ZEV) alone are not enough to solve the climate crisis…the path to carbon neutrality by 2045 also depends on reducing per capita VMT (the total passenger vehicle miles driven by an average person in California on any given day).”
They include a graph showing the necessary target VMT for 2030 is 18.4 miles per day.
This 25% reduction is twice what occurred during the 2020 pandemic year. They seem to think this is achievable in the next 6-7 years. At the same time, only 2% of trips use public transit (and that has declined since 2010).
