This is up to congress (who have GOP members who like either UAW or auto company profits/sustainability), but would be a big mistake. US transition to EV is already slow, but models with lower sticker prices than inferior ICE vehicles, and legitimate competition to Tesla, are being released, in addition to much lower operating costs, and future revenue potential from V2G (or robotaxi). There will be no more investment in new ICE vehicle performance or capacity, even in US.
There have been significant IRA related announcements around EV production in US mostly from colonies. Part of the attractiveness for US/NA production is this tax credit. If the US is trying to kill EV market both by eliminating this tax credit, and not investing in charging infrastructure, then the US becomes a shithole country for investment and very high cost production.
This is one of many job destroying, and deficit/debt balooning, measures that are intended, and will significantly impair/collapse US economy such that mid terms GOP will be voted out. The biggest collapsing intent is a war on Iran, which risks high spike in oil prices, that are ironically good for EVs, but they will need to be imported if US investment is discouraged.
Geopolitical headwinds with colonies are global warming, Israel supremacy, and colonial brainwashing to pay more for war on Russia with ambition of cutting off colonial imports from Russia, and increase tributes to US. Biden/Blinken were masterful at pretending to be pro-human, while achieving the above destruction. Geopolitical alliances with US are likely to be much weaker under Trump, though Trump humanizing media promises that every disrespectful order he gives every country will be executed with enthusiasm.
That said, a carbon tax (with dividend paid to residents) is much better than an EV credit. Emissions are based on miles driven. Many alternatives to an EV purchase are available to reduce that number.
