Let's assume that over the lifetime use of vehicle, EVs and ICEs have the exact same CO2 emissions. The EVs still win because the bulk of their emissions generally aren't in populated areas where people have to breath the exhaust, and then have the subsequent health issues (and if they don't have health insurance, the rest of us get to cover their health care costs anyways, but I digress...).

But in reality, EVs, especially when produced using renewables, have lower lifetime emissions, in addition to not making exhaust in populated areas.

While some current batteries from some manufacturers are pretty terrible and may need replaced to restore range, it won't be like that forever. Tesla is working on a million mile battery right now. They're already good for 500k miles.
