Anyway, 22 MPG is nonsense. DOE begs to differ. Of course, the layers upon layers of the deep swamp don't talk to each other. The below is for light-duty vehicles.

Through various research and sources, I've garnered enough information to state that it takes 20 tons (METRIC!!!) of CO2 to make an SUV battery.

It's nice to start out in a hole, eh? Make that up in 6 years, and you're close to buying a new one (or already did) or maybe needing a new battery.

This is so f'ing stupid. It infuriates me to no end.

I read the energy balance doesn't net neutral before about 20,000 miles, as all that goes into making an EV takes a lot of CO2 by itself relative to an ICE car.  After that point, it becomes "beneficial".
See above.

For illustration, the Tesla Model 3 holds an 80 kWh lithium-ion battery. CO2 emissions for manufacturing that battery would range between 2400 kg (almost two and a half metric tons) and 16,000 kg (16 metric tons).1 Just how much is one ton of CO2? As much as a typical gas-powered car emits in about 2,500 miles of driving—just about the same weight as a great white shark! 

(The battery on a larger SUV would of course be larger.)  If the above is correct, a "typical" car emits about 4*5 metric tons of CO2 per year (12,500 miles).  If we take the midpoint on battery CO2 generation, we'd have 7 metric tons to make the battery, or around 20,000 miles or so.  Needless to say, there is a metric ton of misinformation out there.

I'm very glad to be able to see through it.

In such calculations, we're all dependent on "experts" of course, of one kind or another.  Ostensibly, battery CO2 will drop as the grid becomes more CO2 neutral.

To the extent that really happens (and I think eliminating coal would make a difference).

Vogtle 3 is now on the grid albeit at reduced output.  That's it except for V 4.

The 2023 Toyota Prius Prime Could Take 3 Weeks to Recharge (motortrend.com)

It has a solar panel on the roof for $610.  MT claims it takes many years to pay that back.

Polestar, the electric vehicle (EV) manufacturer, unveiled its latest model, the Polestar 4, a compact SUV that does not have a traditional rear windshield.

Instead, the car has a high-definition rearview camera that provides a detailed view of the surroundings to the driver.
The move is significant, even as some cars around the world are eliminating side view mirrors in favor of cameras and screens within the car’s interior to boost aerodynamics and EV range.

That sounds good, until it doesn't work and then what?

I figure if I'm passing everyone, I don't need a RVW.

In California—the national leader in electric cars with more than 1 million plug-in vehicles—EV charging currently accounts for less than 1 percent of the grid’s total load during peak hours. In 2030, when the number of EVs in California is expected to surpass 5 million, charging is projected to account for less than 5 percent of that load, said Buckley, who described it as a “small amount” of added demand.
