Agreed, which is why I begrudgingly accept that local ordinances are appropriate, which can include California setting their own standards which tend to dictate vehicle designs for the rest of the country, since it's the largest market in the US.
I'm disappointed that VW diesel-gate money went towards them owning a near monopoly on the DCFC infrastructure rather than something else, like EV school busses. That more directly addresses what they are accused of; diesel particulate pollution negatively impacting health. Where better to reduce diesel emissions than around all children, on a daily basis?
...and this comment reminded me of the cartoon freebeard shared, probably in the thread that should not be mentioned.

I've looked at the burning of boatloads of fossil fuels every day in a similar way. It's a massive, continuous, massively polluting fire.
I like the way that Jeremy Rifkin characterizes climate change:
*quote*
Climate is all about the shift of the hydrological cycle, the water cycle: for every degree that the temperature goes up on the planet, the atmosphere absorbs 7 percent more precipitation from the ground. That means the whole water cycle of the planet shifts. More floods, more tsunamis, more hurricanes, more violent snows, longer periods of drought—that’s what’s going on around the world today.
Global ecosystems cannot catch up to a shift in our water. Drastic changes in the hydrological cycle leave ecosystems destabilized—and then the animals and plants within those systems die out. So what our scientists are now telling us is that we are in the early stages of the sixth great extinction event in the history of the planet.

CO2 is 0.04% of the atmosphere, humans actually produce a small fraction of total global CO2, and cars/commercial/refineries produce a small fraction of that. The tail doesn't wag the dog.

What are the conclusions that come from what you posted?

I have never seen any self-declared EV fan claiming EVs would doom us, yet once in a while I see some highly-greenwashed EV fan stating that a random Chinese EV could be more "sustainable" than a Honda CG with a side-car and a flexfuel engine running on ethanol
