A number of major carmakers — including Toyota, Stellantis, Mazda, and Subaru — "pooled" their emissions with EV makers Polestar and Tesla earlier this year, in an effort to comply with tougher European Union carbon emissions rules.
So if Tesla sales are collapsing they likely won’t have the credits they’ve already promised to the other guys and I assume will have to compensate them. It’s a double whammy, reduced sales & extra costs.
