I understand basic physics and I'm an engineer in the automotive space. It's pretty easy to tell that ICE has writing on the wall (ICE by the way, ICO isn't a thing).

We've basically worked out every possibility for the ICE. Efficiency is theoretically limited, we know what it's limited to, and we're pretty damn close to that. It's provably impossible to progress on efficiency, and even if we did, they would still be putting out more carbon and NOx than any xEV.

Hydrogen ICE still produces NOx, eFuels require an abundance of clean green energy to be even remotely worth it and those are basically the two paths forward for the ICE. For commuting and medium distance, BEVs are the clear winner, they're also just more profitable than ICE cars, and as more models become available, cheaper for consumers too, so everyone's going to switch anyway.

This ban is enhancing tech progress, as we'll be adopting and improving a clearly superior technology faster with the ban than having to wait for consumers to decide while we continue to pass of the costs of using carbon emitting fuels to the next generations (when they'll have to deal with climate catastrophes rather than advancing tech as a functional society).
