During the demo, the autonomous driving car sped along a closed track and came to a stop for a person wearing a Band 2 that couldn't be seen by regular cameras, other sensors or any of us in the car. Instead, a stop light on the track that's connected to Azure was pinged by the band that it was nearby, that information was then relayed to the car.

The system is Microsoft heavy using the Azure IoT Suite and Cortana analytics for predictive hazard modeling. It also requires a connected car and a connected infrastructure like stop lights and signs. But as Karsten Schulze, senior vice president of active safety and driver assistance systems for IAV pointed out, it's meant to work with all the other sensors coming to cars with autonomous features. So automakers could use it and other safety features from other vendors.

Keeping pedestrians safe wasn't the only feature built into the demo Volkswagen. The driver was also able to access the Cortana voice assistant to check on the weather and join a Skype conference while the car drove itself. It even displayed a PowerPoint presentation in the instrument panel. You wouldn't use those now, but the companies are investigating adding more productivity features to vehicles when they become fully autonomous.

So when the driver-less car hits the road, get ready to start working during your commute.
