California is able to pass laws by simple majority. This means some really radical laws without logical ways to satisfy them get passed, and then repealed if that's the case. Remember the EV mandate from the late '90s (same thing happened then, too). That first mandate resulted in the Honda and Toyota hybrids, and the short lived GM EV1. Honda and Toyota went all in on meeting it. GM made a token effort with the EV1 making only about 1000 of them. The other OEMs decided to just wait it out and do nothing.
As a result, Honda and Toyota developed effective next generation systems which gradually all of the other OEMs benefited from (electric AC, electric PS, hybrid tech, etc.).
Those Toyota hybrids are typically used as taxicabs in most US cities, routinely getting 500k miles on their original drivetrains (astronomical, compared with the previous taxicab mainstream, the Ford Crown Vic).
Toyota has never planned to be against EV, in fact the whole concept of Hybrid was always considered the first step towards electrification, but has maintained that the amount of rare, raw materials necessary to convert the entire national fleet to full EV was out of proportion to what is available globally (and mostly from China). You can build 90 hybrids for the same amount of those raw materials as it takes to make 1 EV.
We'll see what CA does between now and 2035, but all indications are the world automakers won't be able to meet it, due to physical limitations out of scale out of everyone's control (like raw materials from China), and then CA will adjust the mandate accordingly.
Laws are intended to move the needle, but when the needle is moved too far for reality, they can be adjusted.
