Why wait?
How about all truckers cease operations to and from California right now? You know, for the minorities and the children.
My crystal ball has this vision of huge transfer points at the CA border choke points such as Yuma, AZ, Reno, NV, etc. many if not most trailers will switch between CA electric and North America trucks. In addition. CA ports will become a backwater destination. This has already started as shippers have already massively redirected cargoes from the west coast to ports on the Gulf and southeast Atlantic coasts to simplify logistics and reduce costs for supply chains.
The crystal ball started hopping around after that troubling vision. Babbling something about some insane event where NY, MA, CT and NJ did the same thing re. mandating electric vehicles. This cutoff the upper New England states from interstate commerce and they were mobilizing National Guard on their borders facing the wokey states. Even Vermont joined the free states. Too much stress on the ‘ole crystal ball and it just cracked up, err shattered. I think I'll replace it with a magic 8 ball, less temperamental.
