I think there's a more important takeaway here than exactly how many miles it takes to offset the extra embodied energy in an EV powertrain vs ICE powertrain. That number of miles is going to vary on vehicle type, battery size, and most importantly grid mix. Going by electricitymaps.com, there's more than an order of magnitude difference between the cleanest and dirtiest BAs in North America, countries in Europe, etc. So the "break even mileage" might vary by an order of magnitude in various grids also. But people don't want to consider complexity, they want a quick and dirty soundbyte as a proxy for proof.
Rather, I think we need to focus on the message that in nearly every situation, the EV will break even way before the median out of service mileage for a car. Sure, if you are one of the tiny percentage of people whose only choice is to buy 80% coal/20% methane grid mix electricity, buying a Toyota Pious instead _might_ be a wash on lifetime emissions. In other words, the best a gasoline powered hybrid can do is about the worst an EV could do. In every other scenario I have looked at, the EV will have lower lifetime emissions starting from a very low percentage of a reasonable vehicle lifetime.
In other words, keep it simple when trying to fight the FUD. The numbers are there and in the EVs favor for the few people who care to run the numbers accurately.
