BMW factory automation

Kinda cool video of automation at BMW- https://www.cnn.com/videos/business/2018/11/28/on-germany-bmw-orig.cnn-business

I hope they are aware that automation can bite them in the tucus. Elon Musk was real big on automation for his Model 3 factory and it did not deliver. He just built a tent factory in the parking lot and went low tech using real people to build the Model 3 and it out produces the automated factory allowing him to finally meet his self imposed production quotas.

dont follow the tesla saga. the design is done? they are building 5000/week? so why is musk on the production floor? the line should be spitting out 1 car every 2 minutes or so on. i didnt see ANY cars leaving the area in the 60 minute story. they should be flying out the door
