Tesla could use a broadband network provided by SpaceX to securely manage the massive amount of data needed to manage autonomous cars, says one analyst.

Autonomous cars produce and consume extremely large amounts of data, said Morgan Stanley analyst Adam Jonas in a note sent Friday. He estimates self-driving vehicles can produce 40 terabytes of data in an hour for example. Today's self-driving vehicles transmit about 500 times the amount of data as a typical smartphone contract.
