For over a decade, the world has watched in awe as autonomous vehicles (AVs) evolved from science fiction to a tangible reality. Startups have promised a driverless utopia, legacy automakers have retrofitted their fleets with sensors and AI, and regulatory frameworks are beginning to take shape.

The road to zero fatalities does not begin with the car. It begins with the network.
