I would agree with Clayton below, the new Tesla Model D is taking on the McLaren F1 for 0-60 performance. 3.2 seconds can't be ignored and will get better. And battery swap is faster than filling a tank of liquids, so in a race scenario with battery swap allowed it would be an unfair advantage for the EV versus an ICE.
I don't see battery pack weights being a problem, in the Tesla the battery mounted on the underside of the frame lowers the center of gravity and improves the handling. Plus so many heavy components have been removed, engine, transmission, radiator, exhaust system, etc. So I think the weight issue is a wash.
The relevant calculation for comparing fuel costs is to compare vehicles of like size and weight and see what it costs to move them, I think that is basically what the eGallon does. Using fleet averages or assumptions about vehicle choice makes for apples and oranges.
For air pollution, I don't explicit numbers either, but not all vehicles have modern engines or are in good maintenance. I am a big proponent of natural gas for heavy duty vehicles since a big part of reducing pollution is to have cleaner fuels, synfuels are good in this regard as well. But even natural gas has some emissions, particularly when the engine is out of tune and it doesn't take a lot of data to see that zero emissions will result in big improvements in air quality.
