I would like to see them partner with a company who, like Tesla, is a true tech innovator. If full self-driving is going to become a reality I think a closer integration with a low-latency 5G cellular network would be a huge boon. So I'm thinking of a company like Qualcomm who is on the leading edge of cellular data and wi-fi networks. They also have some leading edge AI technology.
But if that's the announcement they have done a good job of keeping the wrap on. So low probability. But you asked.
