I think it's half this and half that Volvo is still a recognizable brand that Americans grew up with. My mother had a Volvo when I was seven. People would react if Volvo was banned. Polestar? What's that?

But Geely can throw down the gauntlet by building Polestars and relabeling them Volvos.

This is probably the reason. Volvo brand is well established in the USA while Polestar is new. So not very Americans would complain if Polestar is banned as compared to Volvo.
