This is just sad for electric cars.
With an electric car, the control of the motor is DEAD simple, and you already have your electrical power. You really need like 2 modules/computers at most. Motor controller that takes DC power and converts it to the phase power to drive the motor, and the "main" computer that includes a PDU and manages the systems of the car.
Optionally a 3d entertainment cluster, but honestly, you can just include a slot for a tablet with a USBc plug from the main computer, and an app, and that would be better than whatever manufacturers are doing now.
