The promises of fully connected autonomous vehicles are great, but so are the challenges.

The synergies between electrification, connectivity and automation in future vehicles are creating new business models and causing developments in each to be accelerated. EVs, for example, need connectivity to assist with finding charging stations and autonomous vehicles (AVs) require significant levels of electric power to support their compute demands. But perhaps the greatest synergy lies between connectivity and autonomy.

Most AV developers, particularly for mainstream applications, want to minimize reliance on V2X connectivity because it might introduce interoperability requirements and a need for standards that may slow down deployment and eliminate competitive advantage. In general, increased connectivity creates cybersecurity risks and latency, coverage and bandwidth issues. Despite these drawbacks, there is broad agreement that AVs need connectivity for up-to-date high-resolution maps as road conditions and landmarks can change due to construction, for example.
