Increase of registration is not equal to profits, Public transportation and heavy duty vehicles are not as profitable as personal vehicles. They are many examples of this before EVs, I don't think is related to quality or productivity, is just because the volume is much lower and the vehicles are less disposable like the personal vehicles. It would be good if they start from the basics, like build a EV truck that can deliver the personal EVs for general public instead of sending diesel trucks to deliver EVs.
