>No, I've pointed out that there are bigger, better conventional cars that get better than 30 MPG. 30 MPG is just a little better than average, and is nothing special in a compact. And the additional demand on the grid being met by burning more coal isn't a contrived worst-case scenario, but the actual situation in much of the world.

You're ignoring real-world values in favor of a fictional baseline because the moment you plug real-world values into the equation, your argument falls apart.

>One thing you notice about this chart is the implicit assumption that you're going to buy an electric car instead of a conventional car, and drive your barely-does-100-miles electric just as much as you would a conventional car. In reality, you're going to buy an all-electric car in addition to a conventional car, and you're only going to use it for some of your short trips. Because all-electrics just don't do all of the things that a car is supposed to do.

Most drivers travel 40 miles a day or less.
