They were one of the first companies to invest into solid state batteries. They don’t want lithium/ non-solid state batteries as those batteries are less safe and have more long term reliability issues. Both of which are core principles of Toyota. They also make some of the longest lasting cars on the road which is better for the environment than you buying a new car every few years (which is obviously not as good as public transit options). Just because other brands have the illusion of caring about the environment doesn’t mean you should try and shit on the one that has a track record of actually lowering their emissions.
