California will still allow sales of Plug In Hybrids after 2035. You will be able to buy an ICE car but it will have a battery attached.

Also, all of the neighboring states will likely still be selling ICE only cars in 2035 if manufacturers are still making them. Sales tax agreements and federal interstate commerce laws make a car sold in a neighboring state easy to register in CA.

If the market is strong for ICE and especially hybrids (which don't have much of a downside) the market can still vote for what they prefer and what makes sense in spite of the 2035 regulations.

BMW probably wants manufacturing close to HQ for the Neu Klasse. There are plenty of other plants that can produce ICE or hybrid vehicles.

Just because BMW is investing in EV tech and production capabilities doesn't mean they have abandoned ICE.
