Market in China seems to be way too competitive for Telsa's approach, they really have wasted their first mover advantage. You can't ride off consumer goodwill forever and not modify/change your lineup according to market demands.
They will only be left in the dust as up and coming Chinese brands are moving and Innovative at break neck pace, while Tesla is moving barely faster than legacy ICE makers.
BYD needs to move faster and take market share away from tesla in overseas market as well.
