Hello guys,
I did purchase a 2022 from out of state, although I did make sure it had all the proper CARB certification stickers and have the copper-free brakes, as I was most definitely not willing to risk anything.
For what it's worth, when I passed by the DMV for the visual inspection, they checked under the hood for the CARB sticker, but I don't believe the DMV employee looked for the copper-free option, nor did he visually inspect the brakes.
Of course that doesn't 100% mean that option is never checked by DMV, but in my case it seems they didn't check, or didn't know to check
