Hey, I know, NAT.
We are currently designing a security architecture for cars that use IPv6 for their internal communications. For this internal communication, you may use this ULA-like prefix. If external connectivity is required (which will be the case), this may happen by dedicated ALGs or proxies, making sure that the safety-critical internal communications is not affected adversely. Filtering traffic would be easier using something like ULAs. Direct, unauthorized access to the ECUs is therefore unwanted and unlikely.
