Why do these sorts of studies always measure the cradle-to-grave CO2 output of EVs to only the CO2 released per gallon of gas in the ICE?
Very rarely do you see the studies that include factors like CO2 released in extracting, shipping, and refining the oil in the first place. The CO2 released when fighting wars in foreign countries to insure access to said oil. The CO2 released in making the ICE car in the first place and all of those supply chain issues like people always bring up with EVs and renewable power systems.

Roughly speaking 50% is a good estimate, but it varies quite a bit based on your assumptions. Similarly the gasoline lifecycle + ICE engine, gas tank, and transmission should be compared to the battery + electric motors + electricity not just the battery vs gasoline.
