Mass Public Transport > Electric Cars.
Electric car support will take a short while to implement, but fossil fuel reduction will take a long time to show and a long time to be significant.
But Mass Public Transport takes a long while to implement and savings are quick to show, that would be because less people would require personal cars, which means direct drop in fuel usage per person, even more so in big cities which suffer because high population density requires too much parking space that is never enough.
Mass Public Transport could undo plenty of harm caused knowingly by the auto industry. funding, or in this case legitimizing the industry will not really help as electricity itself is still generated from fossil fuels.
The solution should be LESS consumption, not making excuses for the same consumption, or legitimizing more.
