VW issues in China are particular to VW in China. Bad software combined with perception in China that VW has low tech where market demands leading tech. And conventional styling where China demands very expressive progressive styling.
VW has two partners ready to make 300k ID BEVs each year but no joint venture Gigafactories. Those partners can sell battery cells to other automakers or manufacture vehicles for other automakers. Not so with GM in USA.
China also has dozens of brands/companies of EVs with large production capabilities. The US does not.
GM has the right product for the North American market. EV Silveado/Sierra EV, Blazer EV, Equinox EV Lyriq Escalade EV, Hummer EV. And soon Suburban/Tahoe EV Corvette CUV etc.
Ramping will not be easy. Saying that ramping to 2M will take longer than 3 years is reasonable. Saying that GM has zero chance of selling 2M EVs in 2025 or that GM will only sell a handful of EV in 2025 is just plain stupid.
In the US we are in land grab situation. Product need not be perfect. Demand for EVs will far exceed Tesla's ability to manufacture EVs for North America. Particularly with the new IRA law. You simply can't import millions of EVs from China every year at a $7500 disadvantage.
