Saw this the other day.
Intriguing. Some people in my industry (IT and business design) hail Musk as some sort of faultless design guru. Thing is, he is a great visionary, but he is not faultless. His cave rescue submarine was a barmy idea for example and a good pointer at his attention seeking personality.
There are a lot of groundbreaking ideas, design features and manufacturing innovations in the Teslas, particularly the Model 3. But I believe if he swallowed his pride and went to Toyota, partnered up and let them review his design for true mass production, they could build that thing for around half the price at twice the volume, which I think is th point of this video.
Musk and others made their fortune with great ideas, building billion pound businesses and selling them on. I think now they are on the cusp of profitability, it may be a good time for Tesla to sell to or partner with an established manufacturer.
