If that were true, then how do you explain the outcomes of the current EV incentives? Has the average price of BEV's in the US gone up or gone down? Has Detroit been able to produce an affordable, reliable, attractive BEV, with those incentives? $7500 per vehicle should have put a lot of "butts in cars", but it actually hasn't for them. They had the competence to build, the dealer and advertising network to promote and deliver, the service bays to address issues, so why haven't they delivered?
The one manufacturer that doesn't qualify for those incentives anymore has still managed to take the lions share of the market and continues to raise prices. Tesla are not competing for Civics/Accords/Camry buyers, they're going upmarket, and the average income levels of their buyer demographics bears that out. They have a huge headstart in material science, in technology, and didn't sit around making compliance cars with their thumbs up their collective backsides for the past decade, like the encumbents.
So this fictional narrative about "volume generates lower cost models" is bollocks in this instance, and could use a kickstart by good old mommy government. We tip the scales all the time on market forces, Tesla already has great tailwinds at their backs. Let's put some wind behind others, maybe it'll even push Tesla to finally get serious about producing lower cost models.
Going back to some of the original counter proposals to the current BBB:
Lower the AGI for qualification, lower the MSRP of the vehicle.
While I appreciate alternate perspectives here, they don't pass the logic and reality test IMHO. With that, I'll relinquish the mic and let the rest of y'all parley over what is surely NOT one of lifes biggest existential crisis ;-)
