There are big tariffs on Chinese made EVs in the US and Canada. just like there were on Japanese made cars years ago. When you start to see Chinese EV manufacturers setting up shop in North America the politicians will be on their knees waiting to BJ them so they would set up shop in their jurisdiction. That will be the beginning of the end for many gas vehicle manufacturers.
The Chinese EV manufacturers are not in a hurry to sell in North America, they sell out all they make now and there is a waiting list.
