It depends on the alternative state of the universe. If the alternative state of the universe is you never drove the car, then you're right, this is not clearly better.

If the alternative state of the universe is you drove the same car but burned gasoline that was drilled out of the ground, then this is much better.

If you have a mechanism that can extract atmospheric carbon, at scale, without any additional emissions (which isn't really what this is...), then that carbon needs to go back into the ground, not back into the atmosphere.

We don't _just_ need to stop carbon emissions, we need to get the atmosphere back down to ~250ppm, from the current ~412ppm - we probably can't afford to wait ~two centuries for it to weather out naturally.
