Good point. However, Tesla also missed its 2015 production target because retooling the factory to produce Model X and to produce more Model S took longer than expected and impacted the existing production line at the same time. I think the exact same thing will happen with Model 3, only moreso given the huge ramp-up needed. Rather than linear growth it's probably going to be more like big staggered increases.
