20: Smart Factory
Another place that automakers changed the game was in their factories. These places used to churn out vehicles built by hand. But with all the new robotic technology, a car can be built in many hours. 3D printing has helped tremendously in the types of interiors and features that can be built in-house (via Forbes).
This technology also helps automakers save billions on R&D, leaving a lot of money on the table for other things. These areas are more advanced than ever, and the new technology goes into a more advanced vehicle.
