They are not going to get the adoption they want because they are attacking from the wrong angle. Their new regulations intend to drive down the number of ICE cars being made and drive up EV production, but the issue with EV's is all in their price, and this regulation does nothing to address that. Most folks (especially in this economy), cannot afford to spend $50k+ on a new EV, this is why used car sales have been so steadily high, folks just can't afford these new expensive cars.
I see this regulation backfiring, all it's going to do is keep older cars on the road longer.
