> I believe one of VW, Mercedes Benz and BMW will bankrupt in 5-10 years. None of them have taken EV serious yet and I fear it's soon too late.
Then you have to believe that also Ford, GM, Toyota, and other will be bankrupt in 5 to 10 years.
VW is next to Toyota the biggest car seller in the world, with Toyota currently the leader. BUT they are not doing cars only, they are also in commercial vehicles.
Second, also those car manufacturer have one big difference to Tesla, they have working manufacturing plants that build cars at a much higher automated level than Tesla does. VW has manufacturing facilities where one car is a sedan with the VW brand and the next one a convertible with an Audi brand. Tesla can't even produce Model S and Model X on the very same line depending on demand. They have separated lines.
The very key knowledge of all the existing car companies is production, and running production lines. If they want they could easily produce also other products that requires comparable assembly.
Actually, the car companies do not really care about the type of drive train. They care about the profit. They could fit any drive train into almost any car easily, when they want and if this would provide profit. But electric cars are currently have no profit. That is the problem.
By the way, most automotive knowledge is also by the TIER1. Did you know that e.g. the Model X braking system is developed, build, and delivered by BOSCH?
Also that most of the design of the manufacturing plants is provided by German companies, which is an open secret in the industry.
