You're so close. So very close.

If company A uses gas, they have to pay a little more carbon tax, and that extra costs end up in the final product.

But lucky for you! Company B also exists, they crunched the numbers and found that over the life of their vehicle it is actually cheaper to use EVs, in their case their end product is a little cheaper than what Company A could provide.

Then you go to the store and you see option A and B, you see B is cheaper and you buy it.

The carbon pricing model has now worked exactly as economists have been saying for decades.
