I had been planning to buy a new used car this fall, my mind was set on a new Corolla hybrid. And then I read that Toyota had sided with Trump against the state of California on emission standards. My purchase is off.
Toyota has long been a leader in fuel economy and is most likely well-positioned no matter what happens between California and the federal government. The company didn't have to do anything at all, but instead it caved to threats from the Trump administration. It was a stupid move by any measure, and it will cost Toyota dearly. They may have a reputation for quality and efficiency, but now they also have a reputation for folding like a cheap suit. This move has already cost them one sale, and it appears I'm not alone.
There's not a lot of actions individuals like me can take. Finding another car manufacturer to buy from is the least I can do.
