On this site, we have discussed the challenges involved in going from 2,000,000 cars a year to 10,000000 a year or more. Tesla has a huge amount on its plate with new and expanding existing factories thats for sure. The shear volume of vehicles needed is also going to run into the desire of many people for a car that looks/is different from their neighbors. That is one reason you see so many colors, models and trims from current companies. Around here there are a sea of white Ys. I’ve seen a few with modifications to make theirs different. Even Henry Ford couldn’t sell only one color forever. Expansion of choice will have to come at that point, and it will be interesting to see how Tesla handles it.
