To keep them rolling down the road, autonomous cars need all kinds of technology to work together seamlessly. Radar, ultrasonic sensors, cameras, GPS navigation… all are essential to operation. And if you’re truly expecting to step into a sci-fi future filled with robo cars, go ahead and add vehicle-to-infrastructure (V2I) tech to the list. V2I is important because it provides insight into the kinds of stuff onboard sensors might not be able to pick up or handle, such as road conditions a mile ahead, heavy traffic management, and toll collection. But before the whole world goes fully autonomous, V2I still has huge potential to improve our daily motoring lives right now, and it looks like Audi is moving forward with the latest innovations for the modern consumer.
