Tesla has delayed the production and delivery of its Model 3 several times and kept the customers in constant wait for it. The CEO of Tesla can learn a lot from Daniele Benedettelli who has created a completely automatic Lego Car Factory using Lego bricks. The Lego Car Factory allows its customers to pick a color for their car before they start building it.
There are many pre-built components in the factory to get the vehicle rolling off the line as quickly as possible. Seeing the legos in action is indeed a fun thing. There might come a day when Legos will be working in Lego factory to build more Legos.
