v2n.org
V2N is in the standards documents. Vehicle-to-network is one of the defined modes of connected vehicle communication, sitting alongside V2V, V2I and V2P under the V2X umbrella.
That makes this an unusually precise fit. Standards bodies, research consortia and industry associations working on connected and automated vehicles all use .org and all write V2N routinely, so an organisation adopting the name inherits complete legibility with its target audience.
Connected vehicle technology is serious and well funded, driven by both automation and regulatory interest in road safety, with ongoing international standards work.
Three characters carrying an existing technical meaning, on the correct extension for the organisations using that meaning. That combination is rare and worth more than a blank string of the same length.
The name is available. Enquiries welcome.
