This is compounded by the rise of ride-sharing services. Once summoning a vehicle to take you somewhere isn't limited by the number of people available to drive them (and are correspondingly cheaper), car ownership is likely to decline. Many major automakers and tech companies are throwing billions of research dollars into making this happen, and insurance companies are trying to figure out how to survive. For example, a recent patent application shows State Farm is betting on collecting massive amounts of data about you. While they'll no doubt use it to set your insurance rates, they also plan to "send you advice, alerts, coupons or discounts on insurance or other goods and services." Traveler's Insurance is thinking along somewhat similar lines. They want to create "a device that offers specific suggestions for managing errands and other travel. Customers would be able to see a map of 'risk zone' data for places they want to go, such as stores, restaurants and roads. They could then plan the day 'with an eye toward how risky such endeavors may be,' according to the patent application."
