Thus, I dont see the comparison.
Tesla is the current leader in EV. Tesla seems to be stagnating in its design and its competitors are catching up. BYD just overtook Tesla as the best selling EV last month [some say it was a technicality because of delays]. BYD makes its own batteries which lets them lower their costs. This gives them a big edge over Tesla.
This is an article that I saw when I was looking up BYD.
