Rivian founder R.J. Scaringe isn’t too worked up about EV tax credits going away. He is, however, worried that legacy American automakers will pull back too far on their plans to build electric vehicles, saying: “Rivian, Tesla, the Chinese—we have a full-throttle focus on EV. And if you’re doing that as your 10% job as an [automaker], you’re going to be in rough shape in 10 years.”
