Consider that BYD electric buses are #1 worldwide.
Credit to China for taking the lead in pushing EV -- as opposed to the current US administration. However click-bait title such as "leapfrog" is misleading. Pointing that out isn't racism. Not sure why you need to hide behind "racism" when facing criticism.
Leapfrog here is a term used to describe a fact. Chinese companies have leapfrogged ICE manufacturers in EV.
