That's a good question.
My recommendation is.... Having both the OEM and the supplier model, as we speak right now, is not efficient. For example, the life cycle for an electric vehicle made by an average North American company, like GM and Ford, is around five to six years, while for BYD, it's between 18 and 24 months. Having vertical integration based here within North American manufacturing will be required to be able to compete with Chinese vehicles at the moment.
It is doable, but it requires significant investments from OEMs, suppliers and, of course, the government as well.
