A new Chevy Bolt starts at $27,600. The least expensive new ICE car in the US is still over $20,000 and will cost you most or all of the difference in fuel depending on how much you drive.
The real "problem" is that price-conscious buyers will be buying used, and then you need EVs to be a larger percentage of new cars for a few years before they're a larger percentage of used cars.
I doubted you for a second due to a clear, years-old memory of the announcement canceling the Bolt — so I checked and it was cancelled! Only to be brought back, only to be cancelled again. So the current (2027) Bolt is the last model consumers can buy- the factory will be retooled for the Chevrolet Equinox.
