Coal fired electricity plants STILL account for 20% of the US's electricity supply. That EV will do no good if its being powered by a coal or natural gas plant. Our first priority should be banning coal electricity, and convincing the world to as well. But the US must take the first step. It's unacceptable to have coal or natural gas power when we have nuclear and renewables.

Carbon emissions are simple. We're digging stuff up, and putting it into the air. Dig up less and start putting stuff back into the ground. It's possible to get to negative carbon emissions without making overly harsh cuts on consumption. For example, flying releases 1/4 tons of CO2 per hour. BECCS negative carbon emission prices vary, but I've seen estimates at $200 per ton on the high side. This means you'll add $200 to the operating cost for a carbon neutral four hour flight, which sounds extremely doable to me.

If you replace a large number of ICE cars with EVs getting all their electricity from a coal or natural gas power plant, it can still be a big win because all the fossil fuel burning for all of them is now in one fixed location instead of a large number of mobile locations. That gives you a lot more flexibility is adding system to capture the emissions, and more flexibility to upgrade as future, better, systems are developed.
