I am far from an expert in production, but I was wondering what people are thinking about Tesla using popular configurations as trim levels instead of a full custom build by the 400k+ reservation holders? My guess is that most people will add options that will fall in a few standard groupings. Could this help them speed up production by forming production lines with each model when they start building? If somebody wants something specific outside of the trim levels, then they could custom order. Thoughts from the group?
