Not a U turn. The Japanese target mature markets while the Chinese target novel solutions. Japanese automakers are more concerned with reliability and safety than Chinese. They have been waiting for solid state batteries to become mainstream which should be next year or 2027. Toyota has already got EVs that can do 1,800 miles on one charge and 5 minutes to recharge. That's farther than my petrol car can go and less time for me waiting at the till to pay for petrol.
