I search after information about who the car can communicate with others cars and protocols for this?
I know that these subjects are new so they are several start ups and labs in the universities that research these areas and I will glad to know about them.
I will glad if you can help me to find information about these.
I find several things that I don't understand what they are and maybe they are related to the subject of communication between cars, if they are related to this subject so I will glad to know how they are connected to this subject and they subjects that are connected to this subject I will glad to know more information about them
1, UTSP Ethernet (also known as OPEN Alliance BroadR Reach)
2. IEEE AVB (audio video bridging)
3. IEEE 802.1Q VLANs (virtual local area networks)
4. WLAN (Wi-fi local area network)
5. LIN (local interconnect network)
6. CAN (controller area network)
7. MOST (media-oriented system transport)
8. FlexRay
9. IEEE 802.3

We can not give you an answer, as you have not stated what kind of communication is used.
For voice communication, the CB (citizen band) and ham radio (when licensed) can be used.
I do not know any data communications between cars.

I think an open standard is highly unlikely. In the auto industry it is well known that networked devices can be used as attack vectors to take over a vehicle and do things that drivers do not expect and have very little chance to defend against. Think an attack on the radio that takes over the CAN bus and shuts down the engine or applies full braking while disabling the ABS, causing a fatal skid.

Murder by wireless!!
