Not to mention that a big-ass power plant burning gas (or coal or some other fuel) is going to be wildly more efficient than the relatively tiny engine in your car. Economies of scale apply to CO2 output too, so running an electric car on not-green energy is still better than running an ICE car.

'wildly more efficient' is probably an overestimate. The worst coal plants have about the same efficiency as a car engine, and the best natural gas plants have ~double the efficiency.
