Right off the bat, the NHTSA report makes it clear that the V2V system "will not collect or store any data identifying individuals or individual vehicles, nor will it enable the government to do so."
It stresses that "there is no data in the safety messages exchanged by vehicles or collected by the V2V system that could be used by law enforcement or private entities to personally identify a speeding or erratic driver."
However, to create an environment of trust, a V2V system must have a security infrastructure to credential each message, and a communications network to get security credentials and related information from vehicles to system security providers (and vice versa).
In essence, "the source of each message needs to be trusted and message content needs to be protected from outside interference," says the report.
The NHTSA expects private entities to create, fund, and manage the security and communications components of a V2V system. While the NHTSA has identified several potential types of entities, including some specific companies that might be interested in participating in a V2V security system, no one in the private sector has committed to doing so.
