The system being shown was made by Denso, a Japanese automotive products company. The V2V system has been primarily developed at a Denso facility in Vista, CA. Denso does not seem to be placing a high priority on this technology since the engineering team they have working on this is not a first rate team that you would find at a place like Google or a good startup. V2V holds a lot of promise, not only for vehicle safety, but as a way to share other information. Hopefully other companies will develop competitive technology that is better then what Denso has to offer (their system has problems other than what the commentator mentioned).
***** That's what i mean. A mesh network would not have a bandwidth issue, since the signal would be within a few hundred meters at most. That would not encompass many vehicles.
+thinkofwhy well there's actually some problems, one being the congestion of packet exchange which leads to loss of information Li-Fi doesn't have those problems, and i am working on it right now!
