I know then tent is getting a lot of criticism from the public but it is a smart move. The tent gives extra space to add more individual steps to the assembly line and humans are best suited for tasks that are rapidly changing.
I think someone finally realized that you can have as many steps in the assembly line as you want so long as no single step exceeds your quota divided by the time per day. (i.e. need to make 1000 cars per day, no single step in your production process can last longer than 86.4 seconds; but you can have as many steps as you want) In order to make 5,000 cars a week you need to keep your slowest step in your manufacturing process to around 2 minutes. This should be doable.
