According to the Ulysses Group, it can help because it can access motor vehicle location data worldwide. Just in case having our phones tracking our locations all the time isn't sufficient.

Ulysses says the U.S. military and spy agencies should be taking advantage of these services

The defense group offers "cutting edge operational and intelligence services, support, and equipment" to government agencies and other clients. It says that it can "access over 15 billion vehicle locations" across the world every month. According to the group, this data can be viewed "historically" or in real-time. 

In a document obtained by Senator Ron Wyden, first reported by Motherboard and shared with Gizmodo, Ulysses claims to "remotely geo-locate" cars in "nearly any country" except Cuba and North Korea. The firm explains how government agencies might find this data useful.
