Easy answer; EV sales continue to grow, which means those buyers are choosing EV over ICE.Interest rates do matter a lot. If a consumer opts for a lesser priced ICE because the EV it too expensive due to the higher rate environment that doesn't mean that EV's don't sell. It just means the current EV offering is too expensive especially when we're talking the domestics.
The real question is are EV buyers opting for similarly priced ICE instead? You're going to have to dig deeper into the sales figures to find that out.
Heck the market slams Tesla if they report less than stellar quarterly results. "Tesla's margins down!" Tesla's margins are the envy of the automobile industry.
