The biggest emission reduction would be if every person committed suicide today, so you can always reduce emissions more with more radical plans until you get to that point. Using nuclear power and wind with electric vehicles gets you pretty low environmental pollution for society's personal transportation needs. I think it would be easier to green the electric grid than to make everyone in America use mass transit and rebuild our cities. Model 3 bodies are designed for a million mile lifespan and the batteries for around 300-500 thousand miles. 125,000km (~80,000 miles) is no where near its expected lifespan. The batteries are warranted to 120,000 miles. We'll see how they actually wear out, but I believe Elon Musk actually wants to help humans impact the environment less while still improving the human condition. Building cars to last instead of planned obsolescence would be in alignment with that goal. People should really move to where they don't need heating if they want to reduce their carbon footprint. That would do more than any mass transit scheme.
