Wireless devices may be enabled to operate at lower frequencies and higher frequencies such as 30, 40, 70 GHz gigahertz all the way up to 300 GHz or more. Short range communication may be enabled between devices. Cellular communication is enabled to operate in private unlicensed spectrum. Vehicles may take actions or present data based on the communication between vehicles. Autonomous self-driving vehicles which form a self-driving unit may send commands around how to drive in unison such that a car in front braking would cause the car behind it to also brake. These cars may use millimeter wave length communication to signal quickly. Information may be broadcast via WiFi or cellular to other devices on observations including road conditions or traffic. A first vehicle can receive a stream over a local wireless network from a second vehicle where the second vehicle has received the data from a cellular network.
