The exchange of information in a timely fashion is critical to accident prevention in transportation systems. Research has demonstrated that anticipating future collisions by as little as half a second before impact could lead to a 60% decrease in traffic accidents. Moreover, in July of 2015, researchers demonstrated a remote exploit of a commercially available vehicle from 10 miles away while it was on the highway, leading to the recall 1.4 million vehicles; this represents the first known automotive recall due to a cyber-security vulnerability.
