So, when do we get the announcement that VW decided to not spend 4 billion to develop their own EV software and instead is paying Tesla 2 billion to license their software?
While it certainly is probably in VW's best interests to offload as much of this as possible, I suspect this is not going to be easy for them to do with the rest of their current "non drivetrain" hardware architecture.
The Tesla hardware is highly vertically integrated and their software platform is built on that. While the drivetrain can operate independently of other portions of the car, there is a lot of code needed for that to work well and be integrated with the rest of the systems (charging, displays, accessories, etc...). Today VW's hardware is a mish-mash of electronic components from different vendors that are somewhat opaque in terms of operation.
Same goes for autopilot... without the integrated sensor suite, steering and braking, redundant systems, etc... there's going to be a lot of work for VW to do...
