Security concerns and the move to autonomy should spark acceptance, but engineers must overcome challenges in sensor fusion, reliability and security.

Vehicle-to-vehicle/infrastructure (V2X) hasn't lived up to expectations, but many feel it will soon become an important factor for improving safety and autonomous driving systems. To make it successful, engineers will need to create strategies that fuse V2X data with input from the vehicle's sensors while also paying close attention to security and signal reliability.

V2X has been in development for decades, but it hasn't gained traction in part because connectivity wasn't widespread. As modem usage becomes more common, it's expected to grow, driven by increasing focus on safety and autonomy. Safety planners like V2X because it can “see” around corners and obstructions, augmenting sensors like cameras, radar and lidar that are limited to line of sight (LOS) data collection.
