Yes, it will.
I think at the stage today when we are trying to really drive cost reduction for technology, if barriers to trade, especially within North America—I think the buy America regulation is a good example—might force production sites to multiply across borders, increasing costs are not going in the right direction. We need to scale up the benefits of a global supply chain in order to reduce the cost of those technologies. Scaling up and industrialization are how we're going to be able to compete with diesel engines. Those trade barriers are going to go against this cost reduction.
