As opposed to EVs that have considerably larger manufacturing carbon footprint compared to ICE cars? Also remind me what is the percentage of clean energy those EVs are consuming?

Again irrelevant, because even if in a particular place now not much electricity comes from clean energy as they shift to more and more clean energy that improves all the EVs in service there. The ICEs in service will be just as dirty then as they are now. Also, if you do generate electricity from fossil fuels and use that to power cars it can be cleaner than using that fossil fuel directly to power cars. That's because burning it in the car greatly constrains how much equipment you can use to try to reduce or capture the emissions from that burning, because it all has to be small enough and light enough to include in a car. Burning that fuel instead to power generators that feed the grid doesn't suffer that problem. You can put more elaborate emissions control there than you could on a car.

  >Irrelevant except perhaps for collector cars. For cars that are actually used the manufacturing differences will be swamped by the operational differences. You'd be surprised. This electricity needs to be generated, and it will hardly be clean for decades. It also needs to be stored in car batteries. And if the energy is "green", in grid "batteries" - plus all the work needed to support the green energy generation, solar panels, huge grid changes, etc. Both of which are nowhere near available, and it's not even certain they can be supported if EVs go to 100% of cars, neither from a manufacturing capacity wise, nor materials wise. And those need to be disposed too. And they'll need replacement during the car's life.
