I can understand why they would have needed to limit this bill to only the exclusive manufacturers of ZEV just to get it through legislation, but I'm curious whether it would allow the other manufacturers to spin off the ZEV portions of their businesses into subsidiaries and then be eligible to sell directly as well. It is a very contentious subject, but some people argue that part of the reason the existing big manufactures don't put enough effort into making and offering ZEV is because they can't rely on the dealers to actually sell them. Reasons given for this is that the ZEV compete directly with the hybrid and gas vehicles on which the dealers have far greater inventory and profit margins, so they have little to no incentive to sell the ZEV. If ZEV subsidiaries of the manufacturers could be guaranteed a chance to sell them then that might be cause for them to spend more effort on making them work.
