But actually, I probably should have said "highly efficient ICE or hybrid" rather than reasonably efficient. It's been a while since I ran those numbers and the piece of info my brain stored was "Don't get an EV until I can charge it from solar". Either way, my overall point stands - EVs don't actually lead to the major emissions cuts advertised in most real world scenarios.
How many crossovers do you see on the market get >66mpg?
Also, this is entirely ignoring the transmission factors, this is purely a gallon of gas on its own being burned compared to the production at the plant. In reality you'd need to add a significant amount more emissions to the gas as there's tons of trucks having to drive that fuel to local fuel stations all over the place, meanwhile transmission of the electrical energy is pretty darn efficient in comparison.

Given how efficient even something like a coal power plant is compared to vehicle engine (with a transmission, and stopping and going at traffic lights every so often), this is incredibly unlikely bordering on impossible in realistic conditions.
Where are you getting those numbers?
