Well, allow me to add following.
The Investment BMW for instance is taking in the Battery cell part is ver small and won't help them to be what their CEO just announced as the EV market leader. Their main EV investment goes into a modular production line where they can produce ICE and EV on the same line. Thats a strategy we should discuss separately if good or bad.
On the battery R&D and production their investment is that small that it looks like more marketing than anything to me.
So, I don't see how they will differentiate with Batteries. They just announced a fluffy picture of an EV that supposed to be shown as a concept car end of this year with 400+ miles range to be produced in 2021. Lets assume with a successful R&D in a year or so they have a breakthrough but still need to build a production plant for the Batteries and Germany and Europe is very demanding with regulations so you need much more time to get approvals to build it versus US or China. What I am trying to say is that all of those investments, announcements, specs and timelines do not add up.
