exponential growth rates in industrial production are HIGHLY unlikely. At best you will have a step function as additional assembly lines come on. OR you will have a max production ability, with various factors inhibiting that production ability such as part issues, failures, faults and so on. So either the plant is not at full capacity, and there are production issues. OR the plants are at full capacity and more lines are being added. (and you can have the worst of both)
